Magneto 2.4.6 Unsupported image format

When I upload an image in the admin area from the wysiwyg editor, the thumbnails all fail to load.

admin thumbnails

Using the inspector I can see a server 500 error on the thumbnail request:

1 exception(s): Exception #0 (InvalidArgumentException): Unsupported image format.

Exception #0 (InvalidArgumentException): Unsupported image format.

When I upload an image I should be able to see the thumbnail in the WYSIWYG editor.

Solution

  • Check the third party plugin you've got in there:

    Experius\WysiwygDownloads

    Try and disable that to see if the issue is resolved, or make sure it's up to date etc.
