Batch optimization of PNGs for iphone/ipad display as xcode does

Question

I\'m working on a magazine viewer for ipad and I\'m struggling with the performance.

I figured out that the most expensive part of displaying the pngs is the loading

Answer 1

We used Pngcrush to compress huge number of PNGs. You can try this too. And also if you don't need transparency then instead of PNG you can try JPG too. But you may go through a number of trial-and-error process for this, comparing the size and quality trade-off many times.
