first, hello to all-)

i m thinking about of using different alt tags in the same picture who is apeared in several pages.
notice that its the same picture, same with-heigth, in the same folder... but i use this picture in several pages and i m in doubt if i can use diferent alt tags for each page...
i dont know if this is dangerous to get banned from google or other SE.

experts can help here with their experiance...

Nah, it dosent matter, I do it all the time. The alt tages only get counted if the picture is linked otherwise google ignores it.

I dont see why that would be a problem. Seems like a good idea if the pic links actually. I would only recomend that you make sure the alt tag it relevant to the main keywords on the page it links to.

i don't see any problem in that. one picture can have different meaning if put with different texts ... for example a building ... alt tags "our headquarters" or "name of the building" or "the neighborhood" ... i know it's not a really good example ... but if you think farther you'll see i'm right ... so i think that it would not be fair fot it to count ... but as wwwMEMORYnet mentioned ... it would be only fair for the alt tags to actually show what it was about not try and trick SEs

c ya.
