  • storing files in a MySQL database

    I get the impression that its possible, because i have seen vbb do it with avatars.
    how exactly is it done, and what are the pros/cons
    i would like to store images in a database, as well as be able to resize them into thumbnails automatically.
    any ideas?

    I'd just store a URL to the file, and not the file itself.

            i used the vbb avatar systems as an example
            basically, you set up a form with "file" type input and enctype="text/multipart" in the form tag. then, the script takes that, inserts the various auto-created variables into the database, and outputs whatever.
            to get it is a simple script as well-- here they are:

            insert:
