I have an icon that I have to submit to Apple for its Web Application Submission process. ? The image has to be full sized (at least 128x128 pixels), and be a PNG that includes alpha transparency. ? I have the image I want to use and I've used this image hundreds of times before, but for some reason, it isn't working now as I am given the error message:
"Icon image upload does not contain a recognized alpha channel, please correct image."
