I guess it has to do with the read permission for everybody, and not 
with the execute permission. Can the files be read by the user under 
which apache runs?

The mime type is stored in the database. As those images were detected 
as text/plain in the past, they're still listed as such. They would be 
correctly detected if you reuploaded them today.
