If you need just a list with an image and a short description, you could use (i.e.) MyLinks as a base, and hack it removing those fields you don't need. Step by step you will reach the result.
An xoops.it user, without any knowledge of PHP or programming in general, has created a simple hack of MyLinks to complain his need to list "Associatons".
He has followed suggestions on what to change on files to have a perfect 'clone' without interferring with original version (suggestions are HERE, in italian, I will translate it if there's a need), and began to dig on files. Or you could download it and compare to original MyLinks files to discover how change and what.
