Wa alaikumussalaam,
You have to copy the links of the picture and use the Insert Image icon at the top. If the pictures doesn't have a valid link yet, you may upload them in a free image hosting website like photobucket.com and others. Goodluck sister. Looking forward to seeing the images.
You may also refer to the Help Section of this site. Insha Allaah I'll look for the direct link of the how-to insert an image thread.
