Thanks, I'll look into that. Also sorry for replying late.

Yea sorry I just found another method, I put paint.net as my default app for opening photos and this way it lets me select multiple and then by clicking "open" I can actually open multiple images at once. Image 1 Image 2 For example, do you see that in Image 1 there is a white country (Bearn) next to that green country (Navarre)? That white state should also appear for example in image 2, so what I would do usually with a few slides is select the area with the missing part, copy and paste it into the slides that don't have it. Also yes, the correction has to be placed always in the same place.

Basically, I'm working on a project which involves slides and I have several hundred slides; but many of those have little mistakes which can be fixed easily by pasting the correction in the wrong slides. Even though you can open multiple files at once, it would still be extremely slow and painful to open each file and paste in it the corrections. Is there any way to paste something in multiple files at once?
