I am having an issue with certain pictures going blank after I use the /Sil command. It is always the same three pictures, the rest of the images I have uploaded are working fine. These blanks are also blank when others view them. I can pick the picture up and click it in my inventory and the image will return for me when I place it again, but it is still not visible to others. File sizes for the images are small, with two being around 36-7k and one being 74k. Two of them are on small wooden signs and one is a portrait picture frame. All pictures are jpg format and the only thing in common I can find between the three images is that they all have a high proportion of white or light colors in them. I have attached the images here and the image host I am using is Flickr.
I will add to this post if I gain any addition insight on the issue.
