Easy. When you left click the render button and get the animation render options panel, in the section marked channel files you have entries for the color channel, alpha, and depth channel. On the color channel line, click on format options and set it for full frame uncompressed (better to do the compressing as a last stage in Premiere or After Effects; compressing already compressed images can lead to artifacts) and click ok. Then hit the browse button to choose where to save the images. Name the files, and select the extension type you want; I'd go with bitmaps rather than jpegs, just so you don't get compression issues. Click okay on that panel, and the entry in the color channel window should be 'title.extension'. After that, just hit the render animation button and away you go!
