Determining which page an image is on

Question

I am trying to replace all the images in a document with a different image. To do this, I am looping through all images in the document, getting the image bounds, determining which page the image is on, then using that information to create a textframe and place a new image. I am using this code to determine which page an image is on:
pageImageIsOn = myImages[ imgNum ].parent.parent.parentTextFrames[0].parent.name;
Sometimes, this gives the opposite page - I am not sure if it is giving the opposite page on the spread, or the wrong number because the textframe is linked to the page opposite on the spread.
The textframes are created dynamically in earlier parts of the script.
(the reason I am using this approach is that the original images are inserted in xml elements - they are placeholders - the replacement images are placed directly on the page)
Thank you.

Answer 1

Thank you - however, after experimentation, I think I need a different approach. Mixed facing pages is not the only obstacle. This is a toughy!
What I am trying to do is use placeholder images in xml elements (placed during rule processing of an imported xml doc) to mark locations for other images that will be placed in a second pass. These new images will be chosen based on the tag content.
I cannot place images based on content the first time through because they end up inside the xml element, and so cannot be floated in the margin.
My first approach involved looping through all images in the document (myDocument.allGraphics) and replacing them based on the content info I recorded in the initial doc processing - this ALMOST works. Unfortunately, they are not exactly in the right order - sometimes, they are a bit off, especially when content spans multiple pages.
I tried copying the placeholders into an array the first time through - however, the images in this array do not allow access of the page information via the heirarchy above.
Is there another approach? Thanks again for helping.
