Convert Images to Base64 TextMate bundle The page is in Catalan but the bundle is in English and pretty self-explanatory. Just drop the .tmCommand bundle file on TextMate. Then you can select some CSS or HTML that contains references to external images, hit Apple + control + B and they will be encoded as base64 and embedded with the data: protocol. Killer. Completely eliminates the need for that AppleScript droplet I was about to release.
