My rule of thumb is to add ALT tags to images of importance; i.e. images that link or say something. Any navigation or headers need ALTs, any logos, and any 'big' images. Anything extraneous need not have an ALT tag, for instance the top left rounded corner of a DIV.
You could spend weeks adding ALT tags to every image, but it won't matter if you can't give it a good description other than "Bottom right footer".

I totally agree with that
