Oh, cuz even fresh images I use dont work with dear friend or https stuff, and Ive tried all the flash player versions
Can you use any of these as a background image: https://www.ttursas.com/DDR/Backgrounds ?
Or do these work for Dear Friend / Metamorpheus: https://www.ttursas.com/DDR/Metamorpheus ?
If these work (they work for me) then the issue might be with the website where the images, that you are trying to use, are.
