Hi, 

I would like to show data uri images like this in canvas object. 

<img src="data:image/png;base64,

IE8 can display it as a regular image but I cannot use this as an argument 
of function drawImage. I see only the default 'missing image' sign. 

Is it possible to display it on explorercanvas? 

What version of the product are you using? On what operating system?
- explorer canvas R3 

Thank you

IE doesn't support data URIs in the VML image elements, so I guess this will 
never work 
before someone finds another way. Someone proposed a patch to use divs instead 
of a VML 
image, you maybe should try this one.
