I have the latest WP. Been using it for a while now.
I would like to know how I can modify the Upload Media/Image iframe width when it pops-up when uploading an image to a post?
At the moment, it always opens the same width, and will vary it's height.
I have been looking everywhere in the code with Firebug, but to no avail. It seems to default at width 640. But I cannot find where to modify this value...
