A reasonable limit may also depend on the display size of the image it is replacing. Opera (and probably other browsers) will try to honor a layout (or stylesheet) even when graphics are turned off. If it was expecting a tiny icon, then even 3 letters of alt can be too many. They either get cut off (and are almost useless) or overflow and cut off the next piece of content (which is often more important). This is more of a problem with table-based layouts, but it isn't restricted to those. I tend to see it in discussion forums and bug reporter tools - which really do show tabular data. Obviously, this problem can be avoided, and it probably is for most people who are unable to see the images at all. But for people on a slow connection, or with mere difficulty seeing the picture, it is fairly common to turn images on selectively -- and then alt-larger-than-image can be a problem. So as a guideline, try not to take more space with the words (even in a large font) than the image would require if it were shown. -jJ
