Richard,
When you go to create your next post look at the toolbar across the top of the post box. Look for the square that has what looks like the sun and mountains in it. Click on that icon. Then click on the center of the box that says (Or Click Here) and then choose your photo that is saved to your phone or computer and upload it. My experience is that it has been extremely easy to upload photos. Some oldheads have spoken of it being more difficult in the past, but now it is pretty easy. If you have any other troubles either send me a personal message or just respond in this thread, I really want to see your great cooks from down in Costa Rica!
