It's really easy from iPhone! It's the only way I do it. All you have to do is click "desktop version" right at bottom of page, which takes you to the full website, then when you do a post click "go advanced" if it's in comments you want to post, once you have done that, write you txt and then click on the tiny paper clip symbol, then a new window opens, pick your photo from you camera, then click upload on the right, once you have done that close that window and submit your post. Hope that makes sense it sounds really complicated but it's not at all X
