Add pictures Pictures can be in .bmp, .tif, .gif, .png, or .jpg format and accessible from your computer (e.g. your hard drive, or a CD-ROM etc). Click Browse and locate the picture you want. Double click the picture to select it. This will add the picture to your ad. Pictures can only be added one at a time. Repeat this for each picture you want in your ad. Good to know: To help them make an informed decision when deciding to buy, buyers often ask sellers for additional pictures. You can add or change the pictures in your online ad at any time (up to the maximum number).
