Can try ;) but this is more a PHP question than anything else.

1°) have a look at http://php.weblogs.com/adodb -> REALLY good & fast
db wrapper. John Lim is a clever guy ! there is some support for blobs.

2°) the answer mainly depends on your circumstances : hosting,
standard or secure (HTTPS), your level of access to the host, what you
really intend to do (ie show the image as such, on it's own, or as
part of a more complex layout (e.g. say it's a shot of a product on a
product page)

In the long run, I believe that the simplest/more reliable would be to
1- write the blob to disk as a file (xxx.jpg is it's a jpeg) and
2- send a HREF link to it as part of an IMG tag. this way your turn
around a really difficult long standing IE bug when you try to PUSH
some data to your user's browser.


3°) now, that being said ... you should also consider whether or not
is is worthwhile having the images INSIDE the db, and not simply have
a link to those, stored on disk. Again this depends on many factors
but remember that blobs tend to ... bloat a db pretty swiftly, making
a backup & restore process that much more difficult (look at the
current thread on gbak on firebird-support)

You'll thank me if I made sense at all! :)
