Getting reference to an image to set the align tag

[james_crane]

Hi,

I have an editable div. If I insert and image and explicity give it an
id I can reference it and change the tag thus...

var imgTag = document.getElementById("james")
imgTag.setAttribute('align','left')

However, I would like the user to be able to select the image, and then
have the align attribute set BUT I can;t get a reference to the image,

I have fiddled with
imgTag = document.selection.createRange()

but am failing - help woudl be appreciated

Thanks

James
