I donít think your problem is related to your PC, it sounds more likely that the image is the wrong size or the file is too big.
Your photo must be a jpg image. The program will refuse any other file extension. Your photo should be 100 by 150 pixels (width by height). We will, if necessary, crop and resize your photo for you - but it will often take longer for it to be approved. Your photo image should be less than 5K in size. The upload process will not allow a photo greater than 10K. If the image falls between 5K and 10K, we will attempt to compress it for you - but this will, again, take longer for it to be approved. If you cannot get your photo below the 10K limit, you should post in the Q&A Forum and ask someone for help. Be sure to specify what graphics programs you have available.
