Exporting graphics/images at full-resolution?

Question

Good morning.
So, I've got a series of indesign documents, all of which contain various different types of placed graphics; eps, png, jpg, ai, psd, and the like.
I know that I can export these graphics from Indesign server, via script, by iterating allGraphics, or, splineItems, just to name a few.
What I noticed, though, is that the exported file is sized to the frame it was placed in.  In other words, if I placed a 3000x2000 px jpeg into a 320x240pt box, did some fitting options on it (say, fill Proportionally), then the exported image will be just that, 320x240.
How do I go about exporting these Graphics at full-resolution? IE: I want my exported PNG to be 3000x2000.
Suggestions?
Thanks.

"An odd way to use ID…" -- That brought a smile to my face. Perhaps, odd, yes, but I've done worse, believe me.
There is a valid reason I have for not doing a collection, and pulling out the orginal assets/Links. I require them to be PNG.
InDesign server does a bang-up job at converting all EPS or AI or PSD files into PNG when I ask it to, but, it does so at a cost: It shrinks the exported/converted files to fit the size of their containing frames. Poo.
Here's a snipperoo of what I'm doing. Perhaps someone else has done the same, and figured out the full-size problem I'm facing.
This is part of a larger script, I've trimmed fat for brevity
(function(){
    var graphicExportDir = new Folder(source.path+"/graphics");
    graphicExportDir.exists||graphicExportDir.create();
    d.allGraphics.each(function(graphic){
        // Can I do something, here, to get my pal InDesign server to export at full-res?
        graphic.exportFile(ExportFormat.PNG_FORMAT, File(graphicExportDir+"/"+graphic.itemLink.name+".png"));
