OK, what it looks like is that the path to your image file is being stored in the database, and you're outputting that path inside of an <img> tag when you output the HTML. That's fine, and is the method I use all the time. Now, back to the original question. You want to overlay some text on it as a watermark? For that, you need to use the GD functions. First, use GD to load in the image. Note that the path you use to open the image here won't be the same as the one you have in the DB. That's because the one in the DB is the path that is available to web browsers to reference your image, which is uses relative to your web page. For example, if your page was at http://www.someplace.com/somefolder/page/php, and the image tag looked like <img src="images/image.jpg"/> the browser path to the images would be http://www.someplace.com/somefolder/image.jpg , but the script path to your image would be very different, such as one of the following: * c:\xampp\htdocs\websitename\somefolder\images\image.jpg (xampp on windows) * /var/www/html/websitename/somefolder/images/image.jpg (linux) * /srv/www/websitename/somefolder/images/image.jpg (linux) * /home/websitename/somefolder/images/image.jpg (linux) Those are only examples, and may not necessarily be the exact setup you have on your server, you should find out exactly what the server is running. You can also reference it via a relative path, which is relative to the PHP script. With GD, you can either save a duplicate of the image with the watermark on, with a useful name such as watermark_image.jpg, or you can output it directly with the proper headers. If you do choose the latter route, you should ideally make a separate image script for making the watermark image, and in your image tag, call it with something like: <img src="image.php?image_id=id"/> The id can be whatever id you've got for the image in your database, and then in your image.php script, make the DB call that grabs the information for that image, and create the watermark. Just remember to make sure you send the right headers or your image won't show! Thanks, Ash http://www.ashleysheridan.co.uk
