A ‘Draw’ document mostly contains more the one slide (page). Yo can’t select across pages.
Reducing the question to one page:
There isn’t text and images, but shapes of a few (22) different subtypes.
All the shapes I know from actual usage, including those created by importing an image, accept (primitive) text. A bit more specifically prepared for text to be filled in are TextBox shapes.
Thus I understand your question as: “How can I select all shapes on a page, but exclude theTextBox shapes?” Is this what you meant?
If your text boxes are rather few and not too small, you can select all shapes (Ctrl+A) and then de- select from the complete selection the single text boxes one by one.
A ready-made tool for this doesn’t exist as far as I know, but user code can easily do it.
