Nino you mentioned that the site only displays 400x600, does it actually resize the photo and keep the original 2Mb version as well as the 400x600 version? Or does it simply display the 2Mb file at 400x600 on the fly?
What i'm getting at is can the 2Mb version be removed/relocated while retaining the 400x600 copy? Better still the 2Mb version could be archived out to some other hosting facility.
