Thank you for the help!
However I cannot get it to work.
I donwloaded the photoshop file type plugin and not sure what to do with it since it was not an effect and there is no readme file (Yeah I read the sticky.. I think every plugin Must have a readme file) I stuck a copy off in Effects and in the Paint.net folder itself.. I don't seem to have any other 'plugin' folders that I can find. Er.. Of course I unzipped the dll and just moved the dll not the whole zip file.
The other plugin, photo flood and fill I put in the Effects folder.
The template file I have from Ron Woods is called 'RSW T-Shirt.psd' and it is 6,701 KB .
When I try to open this with paint.net it says it cannot recognize the file type.
What am I doing wrong? Did I get the wrong template file or is the photoshop plugin not installed correctly?
