In the Images box, you are permitted to upload one image for free with your listing. The classified system will only accept JPEG or GIF images under 3MB in size; if you are trying to upload an image larger than 3MB you may need to crop and / or resize your image before you can upload it.
You also have the option of purchasing additional images; a total of 5 images for $1.99, or a total of 10 images for $3.99. Checking the corresponding box will expand the images box to include the appropriate amount of image upload boxes.
Image #1 will be displayed as a thumbnail on the ad details page. You also have the option upgrading your listing to display the thumbnail in the search results page as well as the details page (pictured at right). All listings that have images will contain a link to the images in the search results listing.
