These three simple individual extensions are already rolled into Juan's Base64 extension, but I believe it may be useful to some to have access to individual functions for specific needs....
Image To/From Base64
This extension has two functions, the first will convert whatever image is in an image component to a base64 string, the second will load a base64 string to an image component. There is an After Conversion to Base64 event as well
