Hi Eric
Thanks for the response.
I understand this, what I am looking to achieve is as follows:
-Upload image to gallery eg img101.jpg
-2x thumbnails are created, one of 96x128 size (img101.thumbnail.jpg) and one of 1024x768 (img101.gallery.jpg)
When a user opens the gallery, the thumnail jpg will be used on the classic layout as your link. Once an image is clicked the 'larger' image is displayed, and below this where the comments bar is I would then like to have a link to the original un-resised file. Some of the images on our site are 20MB and the full image is downloaded whenever a user views it - this takes a long, long time on a mobile phone or African ADSL connection!
