Few, as has been pointed out, the less secure (IMO) being handling
files to disk, although any number of ways to mitigate that.

What is the intended end use? security & reliability both have
intended consequences (well, benefits). If reliability is the
more important of the two you have to consider what happens if
the system housing the images in the db grows too large to deal
with? what if the db dies and needs to be restored? how much
downtime is acceptable? Are you doing any sort of replication?

How big do you expect each image to be? how often do you expect each
image to be viewed? All important questions you need to ask before
saying the db or the fs is the best place to store the image.
Based on what you have stated, that there will be an expected 10k of
images, I would say you want to go with the filesystem, with an
appropriate
directory split-up (so you aren't dumping 100k files into one
directory).
