A friend gave me some code to randomly update my cartoons on my website.

Code:

==============================================================

Probem is, in the past, I used to upload new cartoon images three times a week and rename them each time to "cartoonoftheweek.gif".

So I had the webmasters that wanted to display my cartoon on their site use this code:

=============================================================
<a href="http://www.strangebreedcartoons.com">
<img src="http://www.strangebreedcartoons.com/cartoonoftheweek.gif" alt="Strange Breed's weekly cartoon" border="0" WIDTH="286" HEIGHT="366"></a>
=============================================================

Problem is my cartoon no longer displays on their website because the random cartoon files now have different names.

How can I get around this?

Can I make either:

cartoonoftheweek.gif = imagelinks[ry]

-or-

cartoonoftheweek.gif = myimages{ry]

I think that will work, I just don't know the proper syntax. That way I can associate the variable to a constant name.

Any ideas? I really need help with this one.

Thanks much!!
