searching for specific pictures in a vast pdf

[AlanJPerks]

I am looking for a way to search for pictures with specific content in a normal text document with pictures.

Can you help with advice on how this can be done (Not using AI)?

This is where my thinking has taken me.

When a reader sees a photo they know something about, they can add data from a selection of preset tags.

Imagine a photo of an unknown person on an identifiable beach. 

The preset tags might be:-

Person

Male  *

Female

Beach   *     Blue Stone Bay

Sea   *

The reader has marked items (tagged) with a * and typed in a specific beach name.

Another reader identifies the Person   *  and adds a name

And so on.

Internally to the PDF, how do you create a unique ID for the picture so the external database with tags can relate to the image?

Thanks.

You can't search images in this way. However, you can create other objects next to the images and then search those objects.

These objects can be text fields, or comments, or something like that. A script can then be used to search all instances of specific tags and present the user with some kind of summary or interface to go to the matching images.

This is a very complicated task, though, and will require the development of a custom-made tool.

That does seem viable.

Am I wrong to believe pictures can become unique buttons to trigger a response?

Alternatively, unique (normal) buttons could be added to the page like your text fields, comments...

The project consists of digitising a large collection of journals dating back to the early 1900s. PDF with OCR will suit my display and text search purposes. For the pictures, I can easily create software for PC, Mac, Android and iPhone to manage the data collection from trusted readers (tagging) and getting the page. The reader can then step back or forward from that point using normal PDF controls.

Does this make sense to you?

Not quite. Buttons can be used to display pictures, but not the other way around. A script can't interact or even detect pictures at all. It can be done with a more complex stand-alone tool, or maybe even with a plugin.

However, don't expect this system to work on mobile devices, since they don't support almost any scripts.
