I keep failing to upload photos. I'm following all the instructions from the top of the Photo Gallery thread and keep failing. What am I doing wrong? So far... * I upload my photo to flickr * press the button above that looks like the postcard * cut and paste the url * the 'IMG' bits appear either side as per instructions * press 'preview post' and all that comes up is a red cross where the photo should go. Any pearls of wisdom???
