dude..i know EXACTLY how you feel!! i was having all sorts of problems posting pics as well . i finally was able to do it the other day (i tried it in the test section). anyway, i know a big thing is to make sure that the photo is NO larger than 125 kb. i had downsized photos to try to make it work but still no luck. then i discovered that the photo i thought i downsized had stayed the original size..what a dumb ass i can be sometimes.
this is what you do:
1)click on add attachment
2)select photo (appropriate size) from your harddrive and dbl click
good luck and there are guidlines in the faq section as well
p.s. after seeing your address...i think this is a conspiracy against canadians!!!!!!!!!!!!!!!!
