Bytes are pretty much stored just as bytes, with four bytes of overhead 
for the length field.  Larger values (> 2kB) are stored out of line, so 
there really shouldn't be much concern about storing the image data in 
the database.  It's probably more of a question what makes your 
processing easier.

       match
