It's a pity that phones recompress the JPG when doing Save To Camera Roll. I'd like to build a system for distributing mini-apps as images, bypassing the App Store. A JavaScript bookmarklet could be used to provide a basic "bootloader" that provides an "upload image" button. Then a binary representation of the HTML could be loaded from the image data. The problem I had was lossy recompression - colours bleed across edges, so the binary data was corrupt after the first save. I'm still not sure how to work around that problem.
