Copyright 2006
 
Here at Goodies we get questions all the time concerning copyright.  Typical are: "A site has a great picture on it, but they also have a copyright notice.  Is it OK for me to use the picture on my site, as long as I don't make money?" and "Even though it's copyright, can I use it just for (family and friends  |  the kids in my class  |  the members of my club)?"
 
Here in the US it is illegal for a person who is not an attorney (lawyer) to offer legal advice.  These questions are matters of law and so it is not for us to say what is legal and what is not.  We can (and I do), however, express our personal opinions on the matter.
 
First, let me say that if you want legal advice you should consult a lawyer, and next, let me say (to the questioners, not to my readers here!) "are you nuts?"  The clue is in the word "copyright".  It means the right to copy.  It doesn't mean "the right to copy and use under some circumstances but not others".  It means that if someone claims a copyright, they reserve the right to make a copy of the work to themselves alone.  If you really want a copy, you must contact the owner of the rights to make that copy and ask them for permission, which they might either give, deny or sell you, with or without some limitations.
 
Copyright law was established and internationally accepted to provide those who create things, such as, among others, painters, musicians, sculptors, programmers, film makers, designers and writers (that was WRITERS -- people who write stuff; like newsletters and so on) with some protection for their work so that when they spend their time doing what they do and providing something others can enjoy, they can reap the rewards themselves rather than have those rewards go elsewhere.
 
"Ah yes," say the technically savviest among us, "but when you view a copyrighted web page, you are in fact making a copy of it on your own computer before you see it."  My answer? .....  "You are perfectly correct, my techno-nit picker friend.  You sound like a lawyer."
 
Here's the deal.  If you're trying to find a way around a copyright, you are probably violating the law.  Why not simply ask for permission?  On the web, this is particularly easy, since you can find contact info for almost any domain name.  If you get permission, great; if you have to buy it, your conscience will be clear; if you are denied then you will have the satisfaction of knowing that you did the right thing and committed no crime.
 
Good for you!
 
 
 
 
 
Thanks for reading!

Q & A Goodies
***********************************
Questions are taken from submissions to our Community
Mentors. You can ask a Mentor a question by going to
http://www.htmlgoodies.com/mentors/
 

Q. I have a domain name that I keep my website posted at. But I also use folders on my site that I do not link to from anywhere in my site. These are just folders for me that I can create pages of reference material that I can look up on the go. I would like to be able to give the address for these pages to certain people but for the most part want to keep them private. Is there any way that I can keep them from showing up in search engines, or some code that would render them invisible to search bots. I don't want to password protect the pages I just want to make it harder for people to stumble onto them without knowing the link.
 
A. You can tell the search engine robots which folders should and should not be indexed by them. It is called The Robots Exclusion Protocol. When a robot visits a web page it first looks for a file named ROBOTS.TXT. This file contain the information about which parts of the site should nojt be visited by the robot.
The Robots META tag lets you tell the robots if a document should be indexed or not:
<.META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
Only a few robots support this way.

Q. I am trying to find a way to post my students' grades to my webpage, while insuring individual privacy.  I have learned from the tutorials how to include a password to keep the grades private.  As far as I can tell, I should be able to make an individual web page for each student and have the password link to that page, showing them their grades. I have 70 students and do not look forward to editing 70 pages each time I have to update grades.  Is it possible to store the grade information in one place and have each individual page find and display the info for the appropriate student?
 
A. You may have already been told that using JavaScript and HTML alone is not a very secure method of protecting HTML documents from being seen by others.  I would recommend that you investigate using a Server Side language such as Perl or PHP.  You can use both to access a flat file or file stored in a database such as MYSQL and then build your HTML document with the students grades.  I know it's not the answer you were looking for, but with javascript you can not read files or write to files.  You would have to store the students data in a JavaScript array and then build the pages from that which would compromise your data.
 
 
 

    
Q. Used this bit of code:
var num=1
img1 = new Image ()
img1.src =
img2 = new Image ()
img2.src = "images/noahnick.jpg"
img3 = new Image ()
img3.src = "images/kevinnick.jpg"
img4 = new Image ()
img4.src = "images/mikekevin.jpg"
img5 = new Image ()
img5.src = "images/noahkevin2.jpg"
function slideshowUp()
{
num=num+1
if (num==6)
{num=1}
document.mypic.src=eval("img"+num+".src")
}
function slideshowBack()
{
num=num-1
if (num==0)
{num=5}
document.mypic.src=eval("img"+num+".src")
}
slide show opens - goes thru each image, after the last slide it looks
for an image that isn't there instead of looping to image #1. Same
problem in reverse Any suggestions?
 
A. Try setting the initial value of the variable num to zero instead of 1.  In your function you add 1 to it as the first step.  Also in your function slideshowUp when num has a value of 6 set it to zero instead of 1.  In your  function slideshowBack try setting num to a value of
6 when it reaches 0 so that when you subtract 1 again it will be set to 5.
 
 
 
 
    
Q. I am sometimes having a problem with software programs that download themselves without invitation. this seems to occur most frequently if I am looking for a piece of music that I can incorporate into  my web page.  e.g. for photo albums.  The most difficult was a programme called gator or something similar.  It made such a fuss with my firewall software that I ended up having to re format my hard disk.  No uninstall prgram came with this invasive software.  The program was like a large virus. It was everywhere.  Needless to say,  I try to be very careful about what I search for, but I wonder if there is some software that I can obtain to prevent trash like this from invading my computer.  Just so you know, I have received help from the mentor community in the past and have always found it to be all the right stuff.
 
A. I am not sure if this is what you meed but it may help:
http://security.kolla.de/
This is a free application that will allow you to monitor and stop applications from loading onto your computer. It will also search for any on your machine and delete them.

Q. I need a well designed homepage that will attract people.  Can you give me some good ideas?
 
A. Make a flow chart of the information you want to give your visitors and list topics in order of importance such as what you offer, contact, ect.  You want a homepage that gives the most important information in a heading to catch the readers eye and then directs them to details.  This details can be located on another page that the home page links to.  Design the home page so the user does not have to scroll to see the main content. The page should load fast so keep the large graphic images down.  There are ways you can break up the squareness of a page so everything is just not in square blocks. You can creat a banner or a side bar with a graphics program such as Adobe Image Ready or Paintshop Pro. Optimize it for the web. the whole site should have easy navigation and a familiar theme such as the same navagation on all pages, company logo etc.. Put your navigation links where they can be easily seen, on the side or top of the page. Your page should have a discriptive title that reflects words used in the heading and first paragraph on the page.

Q. Is there a way of centering  a picture or text in the middle of the page, compared to <center> which puts it only on top?
 
A. Below is the code needed to center text on the page. If you are using a nested table or have other cells in a table and you want it in the middle you can add this to the cell tag:
"vAlign=middle". That sets the verticle alignment to the middle of that cell.
<.html>
<.head>
<.title>Centered<./title>
<./head>
<.body>
<.div align="center">
  <.center>
<.table border="1" cellpadding="0" cellspacing="0" width="100%" height="100%">
  <.tr>
    <.td width="100%" align="center">
    <.center>This is centered on the page.<./td>
  <./tr>
<./table>
  <./center>
<./div>
<./body>
<./html>

1964 The Beatles Arrived in The U.S.
 
The "Fab Four" from Liverpool, England, with their trademark haircuts landed at New York's John F. Kennedy airport on this day in 1964, to bring "Beatlemania" to the United States.  Six days previously, their song "I Wanna Hold Your Hand" had become their first US No. 1 hit.  Thousands of fans gave them a screaming welcome to America.  A couple of days late, they made their first appearance on  the Ed Sullivan Show, again, to a screaming audience.  At the time Ringo Starr was aged 23, John Lennon 23, Paul McCartney 21 and George Harrison was the baby at 20.  Over the next six years the Beatles became a driving force in changes to western society, the effects of which are still powerfully felt today.  The Lennon-McCartney song writing team was acknowledged world wide for their genius.  The Beatles disbanded in 1970 having created 18 albums (including the world's first theme album, "Sgt. Pepper's Lonely Hearts Club Band") and in the U.S., ten No.1 singles.
