As far as web standards, the general recommendation is that any image meant for use on the web be no larger than 100kb (but that really, the smaller the size, the better).The reason for this is that images with larger sizes take longer to load in a standard web browser, and eat up more bandwidth. This can slow down your patron's interactions on your website, and can also lower your ranking in Google's search algorithm.

Roy Tennant posted an excellent "Web Image Size Tips and Tricks", which you can read here: He mentions several techniques to minimize the bandwidth impact of inline images, including:

  1. Adjust the physical size of the image
  2. Decrease the image resolution
  3. Decrease the number of colors/bits per pixel
  4. Use the JPEG format for images and the GIF format for text or line art

    Is it possible to have this document made available to view?
