I am trying to choose a custom cover for my tribute to Keith Flint. But everytime i choose a photo, I get a little red box saying "Image is too small. It must be at least 300x300". I tried filtering my google image search so that it only shows pictures that are 300x300, but that still doesnt work. Please help.
Try cropping the picture you want to use with a program like Paint. You'll be able to see which size it is and will be able to readjust it so it's not too big or not too small. Save it as a JPG as well as this format is supported.
Try setting the image via a different device to see if that makes any difference.
Hope it will work! Let us know if it doesn't or if you have further questions.
