Is there a way to programatically locate all images in a document?

[Henry Stock]

Apparently the search function using the graphics option skips over some
images. I think someone told me there is a difference between inline images
and ones that are floating. My tasks are as follows:

1. I would like to build a macro that will locate each image in the
document and select it regardless of which type it is.

2. Then I want to build a second macro that will left align selected images
and set wordwrap to top and bottom only, adjusting the margins abit so that
text is not too close to the picture.

3. Finally for many images, there is a caption of sorts. I don't know if it
was created as a caption. I just know that the style is listed as
"OP-FigureHeader". I want to ensure that this text, if it exists, is
directly above the image.

The document is close to 300 pages long and there are many images, so I am
hoping to automate this as much as possible.

At this point I have only create one macro mostly through recording and it
is not perfect. the text below implents task 2. I welcome any suggestions
