[Ham-Computers] Image sorting/identifying software?

[KD7JYK DM09]

I have decades of digital images, photos, scan, stuff from the web, et 
cetera.  To sort to some extent, I organize by size, from small to large, 
then set the list to thumbnail view, but I have some that are low resolution 
of a certain size, then higher resolution of another size, and some may have 
had the name changed, so I still may have dozens of duplicates.

Is there anything, preferably in the way of freeware, that sorts images by 
what the image is?  Something that will, for example, see a photo of a 
flower, person, or tree and organize the images, by identical flower, 
person, tree?
