When you're adding text in the box and want to add a picture from your computer just click on the little camera icon in the text box toolbar. Click on the Browse button in the pop-up and find the file where your picture is located. When you find the pic just double click on it and it will copy the link into the pop-up. Click the "Add" button and the picture link will copy into your text box.
That was maybe a third of my Camaros. You should join the Redlines group and check out my Pythons! Have fun!
