Any one here familiar with base64 images?

Thanks for your interest Crazysuna. Base64 is similar to base16 or hex to reduce the physical size of representing numbers. Images are just series of numbers that will be interpreted by our browser, right? If this image can be converted to base64 then instead of sending 2 files we will just send 1 HTML file with the embedded image in it. If you're using firefox there is this addon called "Custom button2" for adding our own button to what ever purpose we like. Check this http://custombuttons2.alipaz.net/forum/ site for other customize buttons. If you edit the button you'll see that its base64 image. There's [base64] button to convert regular images file to base64. We are both in the dark here so I am soliciting ideas and experience in using this format of image.
