Get URL as container - data url

[David Wikström]

It seems you can't use the Get URL as container with the data protocol. Any suggestions?

I'm trying to automate the extraction of images stored on FileMaker layouts to put them in container fields instead; I've got a file imported from the DDR xml where I display the images in the webviewer using a data url; I can of course simply drag-and-drop from the webviewer to a container field, but that's pretty boring.
