Do you mean the 'data' protocol? See K-menu -> System -> Monitor -> Protocols, 
choose 'data'. There are some examples there, and a reference to RFC2397.

If the answer is yes, read on; otherwise disregard.

The trick is to encode the data with base64 (as you and others pointed out). 
On my system (SL 10.1) I have no uuencode, but uuenview. From the example in 
RFC2397, use:

  <img src="data:image/gif;base64,*" alt="Larry">

in your html-file. Replace the asterisk "*" with the output of uuenview -b 
<filename>.gif.

If your images are not gif images, you need to change the mime type 
accordingly. To find out what the mime type of the image is, do:

  file --mime --brief <filename>

and replace "image/gif" with the output

*** Please note: Konqueror 3.5.4, Opera 9.0 and FireFox 1.5.0.7 support the 
data: scheme. I'm not sure if IE does.
