I was curious, I'm missing a bunch of thumbnails for images I have uploaded. I have the STK module, and like the images from online better and have been replacing them. But all of the items look like they're missing, though they are in my handouts. At least on my end they are. Also, if I try to drag and drop the image onto a handout from the asset library, it fails. I've been uploading them using the choose file button on the handout.
