Image Generator

thematking · Jul 27, 2010

Hey guys, i'm trying to make an image generator for my site, so I have used the church sign generator (www.says-it.com) as a template. I ended up having a bunch of errors so I decided to start with the very base of the code and work from there. I copied all the pages into my web site directory, yet I still have an error. When "go" is hit the image doesn't show up and if you press "click here to download," an internal server error comes up. Here is the link to the page, I was wondering if anyone could help me. http://www.thematking.com/residential/doormats/vinyl-link/church.php Thank you.

What is/are the error message(s)? What's the code look like?

Not much we can do to help without those two pieces of information.

Hey, sorry about that. Well the image appears as a broken image, and then when you try to click the download button this appears

That code isn't for the script that generates the image, so that's not really of any use to us.

The errors in the error log pretty well explain all of the problems the image generating script "church.pl" is running into. However, since that's obviously a Perl script, you're probably not going to find much help here. Either find help on a Perl board, or find a PHP-based image generator (or even better - write your own ).

Whoops sorry about that. Well if anyone happens to know anything about this, help would be appreciated. Also, i'm not so sure all the errors are related to the perl script are they?

All of the errors you posted are generated by (or caused by) the Perl script, yes.
