odd url, and difficulty in following the php page flow

I'm trying to understand code that I bought so I can modify it.

In the index.php there are picture links:

<a href="test10,10"><img title="" border=1 
src="makethumb.php?pic=product_images/test101.jpg&amp;w=121&amp;sq=N" / ></a>

I don't understand the href since it is not pointing to a page. test10 is an id of a picture. I assumed it was going back to the index.php and the code would extract the test10,10 from the url, but it's not. I know that because I put in trace code as the first line.

The question is, where is the link going to?

I know it that it somewhere in the process it executes a page called profile.php, but nowhere in the source code (doi开发者_如何学Pythonng a global search) is there an explicit call to profile.php.

As a related question, is there a way to profile the code to see what pages it's calling without using xdebug, which for the life of me I can't get working after many hours of trying every suggestion I found here and else where. (I'm using xampp)

The flow is: you enter the site www.site.com/final/index.php. which displays pictures with the link as above. When you click on the picture with an id of test10 it takes you to www.site.com/final/test10,1

thanks

The question is, where is the link going to?

Under normal circumstances, a request to

www.yourdomain.com/current_directory/test10,10 

is made.

Usually, Apache will try to find a file of that name, and fail.

If the behaviour you get is different, then there is probably a mod_rewrite rule set up somewhere. Look for .htaccess files (note, files in parent directories affect all children) and check the httpd.conf, httpd-vhosts.conf and other log files for any RewriteRule settings.
