I uploaded a gif image into my art library for the campaign VT World. The upload worked fine. I saw the gif properly in the library window. Then, I pull it up on the right side panel when I am looking at my map to drag and drop the image on the map. Suddenly, the only thing the image has is one of those little thumbnail error tags. I just spent 3 hours making two maps that will use this image for tomorrow. I tried to drop it on the map anyway and manipulate it as if it was not showing in error. But it still failed. I deleted it and reloaded it. It worked again in the upload and failed again in the pull up on the right panel. Help!
