I tried destroying all three signs and crafting new ones, and the two small wooden signs appear to be working now. The new portrait frame still will not accept the picture. I also deleted the original images from flickr and reuploaded them, still no luck getting the image to work on the portrait frame. When I use the sil command it says the picture was added to download que then successfully loaded to the sign, but the portrait remains blank. I have tried putting this same picture on a wooden sign and it works fine. I have added other pictures to portrait frames in the previous day and they worked, but now when I try adding one of these other pictures to this portrait frame they also do not display and portrait remains blank.
