suggestions for images size

[cmotor]

I am looking for different opinions about suggested sizes for images on web pages. More clearly, how many KB should my image(s) take up per page. I am targeting 56K modem users.

Thanks in advance.

As small as possible, but still able to acheive some level of quality... It will vary directly with the size of the image.
