I took the liberty of taking Justin's sweet little mod of Allan's tm_dialog example and incorporating the all-purpose CSS drag command code.  Just for giggles.  (Nice lineage, huh?)

It's mapped to CTRL-SHIFT-I right now, and it's actually really handy, especially when there aren't a ton of images in the project.  I haven't gotten a chance to really explore tm_dialog yet, but I'm sure this could do a few more tricks ;-).
