This was broken when introducing loading images from the server. Now it first tries the server and if that fails tries the actual URL. Still, the image does not show up immediately, since the DivePictureModel is unavailable to the image downloader to be told to update the images. This needs to be fixed but in the mean time, the image is shown when the dive is reselected (possibly on the next run) since it is then loaded from the cache. Signed-off-by: Robert C.
