Are you trying to add it to the post or as your icon? Icons cannot be added until you have posted 100 times. As for adding a photo to your post....Click on the blue words FILE Manager under your text box for your post. (You have to be in the full reply screen.) Once there click on the word browse. It allows you to locate the photo on your computer. Write a caption in the box if desired. Then click add file. When you have posted all the desired photos click Done adding files and it takes you back to your original posting box. Until you hit submit you will not see any photos, but they are there. Hope that helps.
