I have replaced Pages 1 – 10 (+ the Regular & Bonus Covers). They were originally saved as CYMK instead of RBG files. In addition, I tried to open those files in MSPaint and save them to JPEG, which automatically converted them into the original colors. However, I instead went to my original TIF files and transferred them onto my slow, 10 year old computer which actually has Photoshop to convert them into PNGs from the source. The PNGs have darker blacks than the JPEG, and they also have much less pixelation, despite the fact the dimensions of the files have stayed the same.
