Please don't top-post - inline or bottom posting (with trimming) is the
custom here.

It does depend (both on the size and usage patterns).

An alternative way is to simply not store images within the database
itself. Store a pointer, and then store the image externally. The
application then gets the pointer from the database and uses it to retrieve
the image from the image server.
