All my photos are done with a 3 meg Olympus C-740. Occasionally I might use my D50 6 meg Nikon but as I stated, doesn't matter the size, if you sign onto the Free Photobucket, in the Upload area is a blue colored OPTIONS link, choose 800 x 600 pixels or less from the list provided. All your photos will upload to that size from then on, be they taken with a 2, 3, 4, 6, or 10 meg camera. Of course the larger megapixel camera you use, the longer the uploads.
Olympus has some great lenses. This was the 3 meg.
