I'm sure that someone has figured this out, as it is a standard feature for Simple Image Gallery Pro, although I can't seem to find it anywhere.
When uploading a gallery through K2 with SIGP enabled and installed, I can view the gallery in the item view and it functions great, however -The enable download original image link in the plugin does not work with K2.
I'm quite sure this is a K2 issue, because when I link galleries via uploaded folder as instructed from SIGP, the download image link works fine. I am going to work on this in the next day or so, but if anybody has already solved it please advise! Thanks
