Hi all.
I'm pretty new to ZenCart but have gotten my new installation configured successfully and running a custom Template (Nifty Zen) with the dual-price add-on also working.

My problem is with product images. I want all the different incidents on my image to look good but it seems I have to choose between having the _LRG version looking good (with all the smaller ones having stepped edges)... Or I can make the smaller ones look good (but I have to give up the full-size image attached to the "enlarge" link.

After much messing around and changing different settings and image locations, I tried installing Image Handler 3.0 and crashed the whole site.

Can anyone give me a hand?
Surely there's a solution to this!
