Thank's for the in depth info Mighty Pete. I know about the problem with resaving jpgs. I always save my project files in uncompressed formats. I only convert to jpg when I want to reduce size such in cases when I want to send something over the net or for viewing on the web. If it's the fact that I used a jpg here that is the source for my problems then I have lerned something new and might avoid using them unless i really have to. The best demonstration of jpg problems in my opinion is to just try and save a page with black text on white bottom. You must look really hard for something that looks more ugly. ;) Gebe: I will do some different test rendes anyway so I will include one without the water.
