Uploading a photo successfuly into your appraisl request is actually quite simple.  Here are some common quick tips which may solve an issue: 1) Make sure your photos are no larger than 800x800 pixels in size.  2) Make sure that file type of your image is either .jpg or .gif. 3) Make sure that each photo's file size is saved in a "web friendly" file size. Do not upload extremely large or supe high quality images - the file size will be too large and you will not have a successful file transer.
