Hi, this is my first post. I have just opened a shop and I am trying to upload the 1200 x 270 pic for the billboard image, but the box just keeps going red around the outside and nothing happens. I have resized it to be out of proportion - however to the size ebay specifies but it still won't load, any ideas why? It is probably something really silly, but it has me stumped! TIA 🙂
