>>61125
Imagine an entire Heyuri page worth of PNGs loading in all at once; approximately 30 images
Those things aren't small! for example, the thumbnail for this image >>61126 is about 6 kb, but as a .png it would be 53 kb!
53kb times 30 is 1.55 mb, which would about 4 minutes to load on dial-up, compared to just 24 seconds with JPGs! and that's not even mentioning how long an image dump thread with hundreds of images would take to load! I could barely imagine!
