Facebook profile picture as .GIF file type?

[fhotoace]

All the digital cameras out there shoot and save images as JPEG, RAW and in some cases TIFF. None that I know of save as GIF. That is something done using a photo program.

The size lens has nothing to do which whether you can see an image or not. If that were true, photography would be in chaos.

As with any file with very little data, whether a 256 colour GIF or 400 x 265 pixel file, you cannot expect to enlarge them and get an quality. you will have to get the original file from your friend (as a JPEG) and then re-size it for Facebook. Remember to save the re-sized image as a different name so you do not overwrite the original.
