when I first started posting pics, I struggled with the same problem - the files were too big. What worked for me was to edit the pictures after taking them. Upload them onto your computer and go into iphoto or photoshop and crop them smaller, just focus in on one part of the picture. Try and crop the pics down about 25% and then save them. upload the saved cropped pics and you should be able to download them to the site. Good Luck.
