it's alt text: a description for blind people and others with sensory disabilities to comprehend the image. I put that there manually-- sorry if the grammar is a little off, I just tried to imitate other alt descriptions. I don't really know how they work

ok so i was wrong i think, alt text is actually there as a substitute if the picture doesn't load properly (either due to slow internet or something)

Oh it's ok dude, I am just afraid of there is an AI analyze someone's art
