The guys in the photoshop forum said IR is better with jpegs. I was looking around in photoshop and the example file name doesn't have any hyphens but it says myfile(space)(insert something not the filename).jpg but not my(space)file(space)whatever.jpg. That should be an easy habit to get into. My thumbnail procedure is: do whatever I need to the original resize to 200x150 Save for Web Sometimes I have problems. sometimes I don't. I will keep trying.
