You can open an account with imgur.com (or any other photo image website) and upload your desired photos to that site. Once uploaded, I click the little pencil on the bottom of the photo when you roll over the photo with the mouse. Then it will allow you to edit the photo for size and anything else. I only change the size of the photo by changing the left box which may have a ridiculous size like 3400 and the right box 2900 mega pixels. I type in the number 400 in the left box then hit the tab button which changes the right box number to correlate to the new size then hit save changes. Then re click the resized photo and a box appears to the right of the photo that says view edit and post. Go to the line that says: BBCode (message boards & forums), then hit the blue box that says "copy." Then come back to SAAC and in the body of the message do a right click which is the code for your photo. Then write whatever relevant commentary to go with the photo (or not) hit save and your desired photo should appear on your thread you created or are responding to on the SAAC website.
