Some PDFs have text embedded in the page along with the image so that wouldn't work. I need to check if the page has image so that the page can be flagged for someone to review the textual content or to add textual content.
If you email me you can test a beta that lets you retrieve a list of all the objects on the page (just the type of each object). That would tell you if it contains any images, but not anything more than that.
That would be a nice feature for the next official update. In case of multilayer PDF, maybe in the future it could also indicate in which layer the image is, thus, in case of OCRed scans, overlaying or underlaying images can be processed separately.
