Description:
Images which have a plus character in its filename don't show as thumbnails,
only the full sized image shows. Probably it's a problem with the URL encoding
of that character and the subdirectory used for the thumbnails.

Additionally, the check usage function does not work because there the plus gets
converted to a underscore, which is of course a different image. The problematic
image is
