Remove ALL Images from PDF Export?

Question

I'd like to remove ALL images from a PDF export (Indesign CS6), with the intention of having the smallest file size possible for review. All the images are Photoshop PSDs.
I have created a PDF Preset (PDF 1.7) that omits EPS, PDF and Bitmap.
That covers any PSDs that contain opaque backgrounds, i.e. are considered to be non-transparent. However, any PSDs that do NOT contain such backgrounds still appear in the exported PDF. I assume they are NOT considered to be Bitmaps?!?
I've gone for maximal compression of images (in the Preset) also just to see how small I can get the file, but it's still over a meg, and I'd really like even smaller. I live in a rural part of England where net access is painfully slow, and even a few meg of data takes far too long to upload, not to mention the constant drop-outs. Consider further that my document is likely to grow by several orders of magnitude and hopefully you can see why I'd like to sort this issue out as soon as possible.
I've not done any scripting but assume it would be trivial to hide images with a script. However, I'm not sure how such a script might know how to make visible only the images that were previously hidden by the script. Obviously I would not wish to unhide images that must stay hidden. Maybe some form of image/object tagging, if that's even possible in this product, i.e. tag them "temp hide" on first pass of the script, and so forth.
Any suggestions much appreciated.

James

@James – to mark the container frames of the nonprinting images by a fill color, you could add the following lines of code in the for loop:
allGraphicsArray[n].nonprinting = true;
//The parent of the graphic is the container that holds it.
//We could use it to fill it with a tint of e.g. 20% of black:
allGraphicsArray[n].parent.fillColor = "Black";
allGraphicsArray[n].parent.fillTint = 20;
But this approach will add a new problem for images, that only use a portion of the holding graphic frame. Or are only partly visible due to a clipping path or a clipping mask or totally transparent areas due to transparent pixels.
Already colored backgrounds will be recolored…
@Sandee – I see the advantage of the PostScript to Distiller way in this situation, but there are two disadvantages:
1. Live transparency will be flattened (could be no issue in this use case, but you never know).
2. The gray area with the big X will be applied also to parts of the images where no pixels are present (transparent pixels in PhotoShop or TIFF files).
To work around all these issues we need a more complex script that is building a  path object around the transparent parts of an image or using an applied clipping path for that purpose and fill that with a gray tint (and maybe with an X).
Here some screen shots to illustrate the problems (with or without using PostScript/Distiller):
1. Original set up:
One placed PhotoShop file with transparency stacked upon the text frame.
The image inside its holding frame is selected.
The visibility of one of its layers depicting a second chair on the left side is switched off.
2. The same setup in a different view:
3. After running the script with the two additional lines of code:
Using the PostScript method would do nearly the same plus adding a cross using the  area of the selected image.
