Idea: to provide simple script API access to placed image information as displayed in the Link Info section of the Links Panel. Especially pixel dimensions, PPI, scale and rotation. Currently there are no simple ways to get this information via script.

Note: if too late for ExtendScript, please consider this while implementing UXP.

I posted this here because this information is something I have wanted for my own scripts, and we get quite a few questions about this on the user forum, too, so it seems like a considerable lack at the moment.
