Based on the error message you gave, I assume the following code in 
~/lib/galaxy/datatypes/sniff.py is presenting the problem.

    if check_binary( filename ):
        if ext not in unsniffable_binary_formats and not 
datatypes_registry.get_datatype_by_extension( ext ).sniff( filename ):
            raise InappropriateDatasetContentError, 'The binary uploaded file 
contains inappropriate content.'

Have you tried adding your 'jpg' extension to the following in 
~/lib/galaxy/datatypes/binary.py?

# Currently these supported binary data types must be manually set on upload
unsniffable_binary_formats = [ 'ab1', 'scf' ]
