iphoto info

Hi all, here is one for you guys, i backed up my iphoto library to a external hard drive , i then did a wipe every thing and reinstalled snow leopard, and the photos that i then reinstalled had gone from being between 2mb and 5mb photos down to 240 x 360 pixels. It is like that on every photo.
why is this happening, any ideas.
Thanks in advance.

thanks macforscience, yes that was checked always has been, some pics are more pixels than others but still a great deal less than the originals, so not sure whats going on.
I am not liking iphoto and this is the better one (iPHOTO 9) so still need help.
Cheers

Hi mac for science, i have found that it seems to be that its viewing the photos in events that i get poor quality. when i look at the pics from photos in the side bar under events the photos have doubled in size.
cheers just thought i would put that out there.
Still not good though.
