Right now AI generated images aren't perfect so there's usually something "off" about them. Too many fingers, weird stuff going on? This one has weird feet and the eyes/look looks a bit like plastic. Everything else looks good.

If it looks too fantastical it might be AI (this one does)
-
If it looks like you think "wow! how come I've never seen this incredible picture before, it's so iconic, (like this one) that it should exist in the public mind by now", then it might be AI.

One can do a reverse image search using Google Images or Tineye to see if, and how many times and when the images have started to exist online.
-There are AI that can detect if it is AI such as this, or this
Usually this one is able to also tell which piece of AI software was used to generate it, now it doesn't. Other detectors didn't really give a high %. (I cut off the text at the top because it was probably added there afterwards by hand which isn't AI so...)
Very soon it might not be possible to recognize them anymore...
