Can you convert an original bit-map to a GIF?
That's exactly what I did. I made both the *.jpg and the *.gif from the same original: a *.bmp image I made a long time ago, when I still used Windows.
It looks like you converted the JPG to a GIF.
I didn't. I really can't explain this since I'm having no trouble seeing either form *.jpg or *.gif on my system with either Firefox or Mozilla. In each case, a right click + "View Image" brings it up with perfect clarity. I've tried several image viewers on my system, and all three versions, *.bmp, *.jpg, and *.gif all look the same.
I never ran into this sort of problem before. Have you tried clicking on the file itself and opening it in a different image viewer? Could the problem be screen res? According to the X Server, I'm running at 1024 X 768.
