This has fantastic potential, and I really need something like this. However, the thumbnails are distorted, which I assume has something to do with the sizing configuration...I can't find the template where I would change that.
This also seems to miss out certain thumbnails...I assume that's because there's also an attachment which isn't the first image in the post and the mod is trying to call that instead? (See attached image.)
Also, it would be great if when clicked the link opens in the same window and takes you to the actual post where the attachment is held rather than just the image.
I really would love to see this in it's finished form!
