'On The Fly' Auto Thumbnailer using GD Library 2.1 in General Add-Ons Support Posted December 2, 2007 Hi there, Just downloaded and installed 2.3b, with a strange result. I followed the instructions word for word and the thing seemed to work OK. However, the thumbnail images on my main store (/catalog) were all blurry/chunky. I was reading here about quality issues and none of the situations seemed to apply to me. I did notice, however, that the thumbnails in my back end (/admin) looked great. Yes, I installed the separate product_thumb.php into my admin folder. Putting 2 and 2 together, I simply copied the product_thumb.php from my admin folder into my catalog folder and boom, the main site thumbnails look great. Im not a technical person so im not sure why or how this works, but if someone can figure it out, im sure others would be greatful.
