Files That Will Not Open In Photoshop

 Sometimes you will get a dialogue box in photoshop when you are trying to open a new file. And it says "Could not complete your request because an unknown or invalid JPEG marker type is found" or " Could not complete your request because it is not the right kind of document."

I don't know why this happens sometimes, but all I can advise is that it may have something to do with the download being corrupted.

I have also found that this is usually an issue with Windows, and very rarely happens on Mac.

The below solution has worked for all customers who have had this problem.

  • Open the  image in a photo app such as Preview (on macOS) or Photos (on Windows). (if you have paint that will work just as well. )
  • Now save the file again as a JPEG or PNG image from within such an app. Try opening the file again in Photoshop.
  • This should resolve the issue. 

This great Youtube tutorial will help you along the way.  It's by KelbyOne.
