could not complete your request because an unknown or invalid JPEG marker type is found

Have you ever had this problem?

"could not complete your request because an unknown or invalid JPEG marker type is found"

Just happened to me and the answer is hopefully simple to cure. It would seem that a file extension is incorrect. EG. you think you saved it as a .PSD but it has become a .JPG. The file looks ok and you can see it but it won't open. Don't know why it happens but the wrong extension causes a conflict. Simply go into Photoshop or your chosen software and go File > Open, select your image file and choose 'open all readable documents' or if that fails, try opening it, one by one, with your most popular extensions like a .PSD or . TIFF or .NEF or .CAF etc if it is saved as a .JPG or vice versa. IE. file name is "landscape.jpg" try changing the extension to "landscape.psd" or "landscape.tiff" etc etc.

Thanks for the tip. This worked for me. Anyone else, your first attempt at renaming the file extension should be the format with which you (or a collaborator) were originally working. In my case it was *.psd and the photoshop had no problem once I renamed the extension back to .psd.

Same error message and can't find a fix - 18 images - one is perfect, the others do not open in any program, no images in windows, all jpegs, all showing size is 2+mb.
