Use a list. UL or OL, doesn't matter.
Define a class for the UL/OL. Define the layout etc, for the LI elements within that class; also for IMGs and Ps. One of the things you can do is to stop the display of "dot" or the "numeral" in CSS.
I use this technique for making navbars, but it should work really well for a set of pics and descriptive text.
