Default How to Encode image to base64?

I need to encode an image in the user harddrive to base64, so that I can send it back to the server as a string in a hidden input field.

Does anyone has a script to encode an image into a base64 string? or can tell me how to do it please?

Thanks in advance.

*nixes have uuencode and uudecode. But if I were you I'd look at the "file" input type. There's a tute at: http://www.cs.tut.fi/~jkorpela/forms/file.html . This will do the job much better, with less processing needed and more cleanly. And it means writing less code. Which is always good ;)

Hi OniShirox

In order to encode a file in client side, you should first open it using javascript, and this would not be possible (due to security restriction) unless you use an ActiveX like FileSystemObject, and it works only on IE.

After opening file by ActiveX, you can read it's content and do anything you want and finaly store it in a hidden text field to be send to client.

Can someone post some example please?

It's ok if it only works on windows/IE.

Thanks
