Haha nice, but I prefer using compresspng.com. Gave me a bit better results with less artifacts when I compared the results of both.
@Kyatric, thank you for sharing that. I read it and I am a bit confused, that is a compressor inside C2 am I correct? But if I used compress images when I import images into C2, does it mean that they won't get compressed by C2 anymore or will it still further compress it? I remembered in one of my older game tests, I wanted to reduce the memory usage shown at the bottom of C2, so I used the website to compress all my images. I was able to reduce it by about 6mb, which was good, but since I never exported both versions out, I never did compare the two performance or image size in the file.
