FYI – I created a form that uploads a photo as well. The name of the photo is generated from the email address (and is stored in the db), but the photo itself disappears.
Well, ideal would be an extra string field in the database for each blog entry, into which you dump a few tagswords when you write your post. WP should then format them on the fly as per a predefined template when displaying the post (reading) or generating RSS.
