Ummmm, is that correct? I thought (although never tried) that you could reference an image as
<IMG SRC="image.php?id=3"> or simular, in which case the headers and everything else CAN be sent in the image tag, which is embeded in a HTML page -- isn't that how they do counters etc etc?? At the moment, I'm just storing my images in my file system, and storing the URLs in my database (as discussed by someone else in this thread), which works fine, as long as nobody deletes the image without deleting the URL from the DB. On the topic of preventing users from saving images, the attempts are futile, because they can also just look at your source to DL the image from it's URL. One thing I have seen work instead of disabling right-click is to have a clear layer (DIV) above the whole page, which (for me) prevents me from selecting text + images from below. Although I don't know how reliable this is.
