When you are making a post, there is a button at the bottom, left side, of the text box, that has a paper clip icon and states: "Attach files" Click that button then a window will open where you can browse to the location on your PC where you have the photos. Select the photo you want then click the "Open" button at the bottom right side of that window. The file should then upload. Once it has finished uploading you can add another photo. I believe that there may be a five photo limit per post. Hope this helps.
