Nope ... Stuffing is exactly like he says ... Cat cat cat yarn yarn yarn ... I said to describe the actual image ... It's totally different, and I've done it on occasion without any issue, but idk how they rank, because I don't let them be indexed.
I figure the person who can't see the image might like to know what color the cat is, and what color the yarn is and if it's a stick figure style drawing or a photo, and if there are knitting needles in the yarn, and ... all the other stuff they can't see.
That's not stuffing; it's describing.
<rant>I even said what I suggested was not a suggestion to stuff ... Idk what to say ... Blown away ... It's the alternative to the image ... Imagine having to use a screen reader ... Wouldn't you like some 'color' in the descriptions of the images on a page? It's been repeatedly states sites should not be built for search engines, so what's everyone do? They throw the suggestion and common sense out the window and try to kiss search engine a** which usually (especially lately) seems to backfire...</rant>
Sorry, just get tired of trying to defend common sense.
