Pinta doesn't recognize images with wrong file extension

[Bartosz Skrzypczak]

Most other programs use somethig like mime type (or some other mechanism that looks at file content) instead of relying only on file extensions. Pinta seems to rely only on file extension to determine file type. And some of my images have wrong extension (like .jpe instead of .jp(e)g).

Would it be possible to fix it and detect file types even when the extension is wrong/isn't available?

To extend this, when I duplicate an image file 'myImage.jpg' I would typically get something like 'myImage.jpg (2)'. This also results in an unrecognised file type for I assume the same reason.

Exception:
System.FormatException: Unsupported file format

I tested with Pinta-1.7 latest build 1.7+r1134-202008032046~ubuntu18.04.1 and Pinta only checks file extension.

This report should be marked as Wishlist, because it is actually not really a bug, but feature request.

If on Linux you can use simple command on terminal to rename files from *.jpe to *.jpg:
rename 's/.jpe/.jpg/' *.jpe

Just a note that this also applies to loading palette files, which have similar logic for checking the file extension.
