Sounds ok to me but keep the pics to a sensible file size, also define the actual size cos it'll screw the formatting up. Maybe a seperate "Topic " and each week as a new "Subject", Topic to be pinned and would it be poss to have a closing date and close to new posts after one week ? errrrrrr what else. Yup, JUST pics, not comments or nothing else. Maybe a short description would be in order. And hey don't lets go crazy and do the same ole thing from 10 zillion angles , post one pic and thats it ! let someone else have a go after that.
You wannit in bullet points I'll do that too .
Wake me up by noon please.
