    Image work is server intensive, you want to watermark them when they are uploaded not each time that they are shown. If you have already a load of images uploaded then you could write a one off script to go through the image folders and deal with them all but you may need to be careful of the page timing out if there are a lot of images.

    its ASP classic

    I dont want to really overwrite the images. I can do it with Photoshop by writing an action. I need to keep the originals for later usage. I want them to be automated.

    I upload them via FTP

    I want to have something like

    image.asp?id=XXXXXXX

    this file opens XXXXXXX.jpg and on the image it watermarks YYYYYYYY in the bottom. This is my point

    You can surely do this, there are many image components out there that could easily do the task. However, as earlier mentioned in this thread, it would consume a lot of server power. Rather, have the image component create a copy of the picture at the time of upload, to which you add a watermark and display when needed. When you need the version without the watermark, you use the original upload.
