Can you query a param() for a picture and then use that to show the picture in html using perl? I want to know is if this is all possible client side. Yeah hope that makes sense.
I have one other question, are there any problems with the client pc running perl modules(right word?). I have no experience using perl in this way.

Do you mean can you create a client application that queries a database and then searches through the code for an image and then downloads that image from the server? Short answer yes. Long answer there are other better tools to do that. But, for Perl use Image::Grab extension

Yes and no.

Yes, it is possible to build a web site which does this and uses Perl to provide the files (image and otherwise) on the server side.

No, it is not possible to do this in Perl on the client side, because browsers do not, as a rule, execute Perl code. Unless you're using a plugin, Javascript is pretty much the only game in town when it comes to client-side code for web sites.

If you want to do this using a minimal amount of Javascript and push as much of the work as possible onto server-side Perl code, take a look at CGI::Ajax for the easiest way to accomplish this.

Yes, "modules" is the right word, but, since you can't run Perl code in the user's browser, this isn't really relevant unless I've misunderstood and you want to write a Perl desktop app rather than something browser-based.

I thought as much. Pretty much self taught, so its hard for me to find out capabilities without asking. I have always used perl/c to deal with files. So guess its time to hone up on my Java again.

Do note that Java and Javascript are completely separate languages which just happen to have similar names...

(Although you can run Java applets in any browser with a (compatible) JVM plugin, so you may have actually meant Java, but I suspect Javascript is what you'd actually want for this.)
