I have been working a little bit with this to try and get it going again. I think I have it narrowed down, when I apply the hack according to the instructions it displays the image as it should but I get an open tag
right next to every image that is attached on the right. This happens no matter how many times I undo and re-apply, I can't seem to find it. I have a feeling this is what is causing the images to load extremely slow.
