longblob-jpg encoding issue?

I have a MyISAM table where I am saving longblobs. These blobs are jpg
files. However, when they are read back, there is a problem in that the jpg
files "have two sof markers."

I am wondering if it is something in the encodings of the table that could
be causing this? Is there some particular encoding I must have this table of
longblobs set to in order to store jpeg data as longblobs? Thank you - Ike,
