you could very well do that, and frankly that is how alot of websites
work.
Yep, including one I run. That site has to generate img and a href links
for visitors, and it seems far easier to return /pics/imagefoo.jpg then
the image itself and decide how to embed that into the page.

Really? In both cases, it's just bits on a disk. In the case where you
don't have access to a shared file repository for your client apps, you

Talk about a decent reply!
For web site stuff, having control over everything is pretty much a
requirement (if you want to do anything non-trivial). The way that I
serve images from the database is by parsing URLs and I've found that
the performance is very good. The fact that I can move stuff

Conversely, MySQL's current 16 MB per transfer limitation may very well

You can just reconnect to MySQL if you get this error. :-) Trying to
