Want to optimize how a list of images loads and scrolls in your Windows Phone application? Jobi Joy, UX Architect with IdentityMine and key contributor to the IRC chat app in the MIX11 Day 2 keynote, returns to discuss with John how he handles image scenarios such as this, as well as how he ekes out extra performance. Jobi has a blog post that explains how such optimization works by using virtualization, caching via Isolated Storage, and working with both preview and full size images. I won’t spoil the episode (it's pretty cool), so you'll have to watch!
