In lower left of screen click on "post reply"
When your reply box appears, enter your response.
Then scroll down to "Manage Attachments" click on that. A new screen will appear with some browse option boxes. Click on one of them and it will allow you to sort through the pics on your puter, click on the pic you want, and then click on upload, when done, click on close this window.
Note the picture size limitations for uploading, you may have to re-size some of your pics that are too big..
