Ajax to download images in order?
I'm fairly new to Ajax. I was reading the book "Professional Ajax" by wrox and I'm making a site that has a lot of PNGs (required for the site). I'd like to use some Ajax to define the order of their download. I'd prefer to download the first 9 images all at the same time, then after that, the remaining 10-12 images one after the other. I read about the Multi-Stage Download pattern and I was wondering if this is what I need. Does anyone have any tips for getting what I need done? Any same sites or code?
Thanks in advance!
