Compress 533mb png images to smaller size without quality loss and rename

I have 880 images that make up 880mb. I need the images reduced into 400 x 800 which is the size of the HTC Desire HD screen size and also convert the image size as small as possible without compromise or little as possible in the quality. Those familiar with pngout [login to view URL] and [login to view URL] should be able to do this very easily. Decent instruction is given here: [login to view URL] I have added one image as an example and would like to see it compressed and sent back to me with details of exactly what you have done to bring down the compression. If the quality is good on my phone then I will accept your bid. Finally I will need all the files renamed. It will be simple case of of Chapter_1_001, Chapter_1_002, Chapter_5_003. An easy task also. I will upload all images for the winning bidder to [login to view URL] for downloading or any other preferred 3rd party site
