Same image makes the following log with stock gallery app: imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error: Unsupported marker type 0xb3 at /var/www/nextcloud/lib/private/legacy/image.php#560

Preview generation should not stop, but skip unsupported images. In current state one panoramic image in the folder can render whole plugin useless.

Start with the preview:generate-all command and the image handling reported at lib/private/legacy/image.php#560. Reproduce the run with an unsupported image and verify that preview generation continues past it; done means the bad image is skipped and later files are still processed.
