When I can’t find an image I’ve made myself I’ll go to the web and look for something appropriate. Sometime I find I’ve captured something and can’t remember the source. I don’t like to post an image without being able to give credit to the person who created it so I’ll try TinEye.
I’ve found this reverse search tool helpful quite a few times and it is easy to use. I open the search window https://www.tineye.com and click on the left hand up arrow beside the bar which says “Upload or enter image URL”
That opens the list of files on my desktop and I select the one to upload. If a match is found it shows the source.
