First of all make sure your pictures are saved in one of the standard picture formats such as .bmp, .jpg, etc. Be sure you know where it is located so you can find it later. Next below where you make a post (before you post it)there is a button that says "Manage Attachments". Click that and a popup window appears. In that window select the pictures you want to add, one in each box. When they are all selected push the upload button and wait for them to load. When they are loaded you will see a list of them near the bottom of the box. Once uploaded hit the post button and that should do it for you. Good luck.
Or use the button that has an icon of a paper clip.
