here is the url to a broken product image
http://139h.silkelegance.com.au/inde...roducts_id=480

you can see the url for the image is pointing to the images\Large folder, the orig pic is in the images folder
url's for all other images still point to the original folder images\

permissions are the same on bmz_cache and images folders,
as it is a win server i have iusr permissions on the folders equivalent to 755, also did try equiv to 777 previously
i can upload product images fine, and IH3 is writing to the bmz_cache as this file exists there
