This gives information about banners and buttons used in advertising:
Caution: ad blockers may block images whose sizes are the same as used in ads.
You may wish to avoid these sizes for any images which are not for advertising. For example, instead of using a
120x60 image, which may be blocked, use a 120x61 image. Note that the ad industry sometimes creates new
ad sizes, so there is some risk that you may pick a size which will later become a standard ad size:
pick an odd size, a size which the ad industy will, hopefully, not later steal adopt. Note also that
the ad standards permit ads of other sizes, but there is less risk that images of such sizes would be blocked.
Caution: ad blockers may also block images whose directory names, file names, alt attributes, or title attributes contain substrings which are suggestive of ads. For example, an image whose alt attribute is the Latin motto per aspera ad astra could be blocked.

Note : the Interactive Advertising Bureau has published guidelines regarding rich media using many of the above standard banner sizes. A disturbing aspect of the guidelines is that recommended maximum file sizes are so high that pages would take excessively long to load, violating one of the key principles of good website design.
Note : visitors will leave a site if it has too much advertising. BurstMedia reported (Sep 2002) that 36% of North American visitors will leave a site with too many ads.
