I have a series of scanned maps (.jpgs) that we need added to our map gallery. I upload the file(s), add a thumbnail, make them public (inc the group), the image and thumbnail show nicely in the opening home page gallery . . . . however when clicking on the image it opens with a small rectangle. Also the image does not show under the Map Gallery tab, and search cannot find it. I suspect it's a directory/group thing. Or does the image need to be tiled? Any tips would save me some time. Thanks!
