question about digital camera

Archived from groups: rec.photo.digital (More info?)

How is everybody. I was wondering weather somebody can help me with
posting pictures with the ones that I've taken from my 3 megapixel
camera. The pictures are in Jpg format but everytime I try to post it
to some site, I keep on getting this error message that says the
picture needs to be in JPG, GIF or some other format or the picture has
to be less than 100,000 bits or something. The pictures are already in
JPG format but I don't quite know how to decrease the bits. Am I doing
something wrong or is there something wrong with the camera? I can post
it to one site without a problem but not to others.
