For some reason when I upload a picture, and place it into the stage area of a page, it doesn't show up. There is a blank outlined box with a picture of a small coffee cup in the upper left hand corner. The picture uploaded fine, but why isn't it visible to the page stage?
If the image has been resized (you can see from the path in the outputted image tag) then it could be SS could not generate a thumbnail for it. Check the permissions on the assets folder. You should have read / write access for the web server.
