It's like file upload but we not upload the file, just read it and convert it into base64 and post it into Webservice or Remote object service. Thanks.

The text has a larger file size than the image itself, and it has to be decoded to be useful. The only benefit I can see offhand is that Base64 text can be embedded in an xml file, which would be useful for small images that people didn't want to host somewhere. It would bloat the xml file somewhat, but for small images it wouldn't be too bad. Can someone more knowledgeable in this area shed some light on the issue? Matt,

I guess I don't see what this buys me... having the image as text based Base64 encoded?
