Hehe. That was a pretty awkward way to work the substitution, I'll admit. Even though I didn't know how to do it the way you just suggested, I should have used the existing PREVIEW variable instead of parsing through the array again. Serves me right for too much copy paste.

With regards to the $? are you talking about the result back from the wget? That part is unchanged from the original script I found. I'd prefer to put the wget within the IF itself, but again, bash is just completely unintuitive to me. It's absolutely nothing like C, Basic, Pascal or PHP - stuff I've used and learned over the years.
