Thanks Eric for you fast replies. So the option fields aren't "known" fields? The problem is apparently the known fields don't provide a large image? Any way that can be fixed or is that on the merchant?
I really need the _e.gif image to show so your idea about writing a code snippet to substitute the tail end of the string is a great idea. Unfortunately I'm not very good at php code. Is this something any php coder could write?
And to implement this code just be paste it into the views section of whatever product list is being displayed? Sorry for the rookie questions.
