Can anyone tell me why my screenshots on Mac Monterey suddenly changed to png instead of jpg and even if I convert them to jpg they don’t show any thumbnail picture now – only the Preview icon? Is there a way to make them appear as jpg again?
I sometimes need to take screenshots of various instructions that include pictures – and in conjunction with training modules related to my job. When they appeared as jpg until a few minutes ago, it was easy to see which picture was which from the thumbnail without even naming them. I just took a couple dozen screenshots and then found they were png with no picture to identify them with quickly.
