    Default Thumbnail size for jpg doesn't change

    I did not found an answer when I searched about this issue.

    When I change the Thumbnail size in the Thumbnail-Option Dialog, the size of the RAW-Thumbnail (CR2 RAW) changes but not the size auf the JPG-Thumbnail.
    The RAW an JPG-files are in the same folder.

    What can I do to solve the problem?

    Is the JPG Thumbnail smaller than the new thumbnail size? There's a Thumbnails option to stretch small images to the thumbnail size.

    Also, some RAW images contain preview thumbnails, while others do not. Change the setting in IrfanView Plugins to load preview images if available, and see what effect it has on the file dimensions and loading speed.

    One usually wants images to load and preview as fast as possible, but RAW images can be big and take a while to decode.

    Thank you very much for the hint.

    When I uncheck the box for "Try to load EXIF-Thumbnail for JPG files" the size for the JPG was changed correctly.
