Search for nodes that contain images

Explain the problem as you see it

Specifically, I've got a series of screenshots I uploaded as part of my weeknotes. I don't remember which day or week they were in and now I want to find them again. I've searched for the text that I think should appear the associated nodes but no luck. So I thought I'd just search for images and then track back from there - except I don't think I can.

Why is this a problem for you?

I'm currently unable to find the images that I uploaded without just going through each node and manually scanning for them.

Suggest a solution

In Gmail I can do: has:attachment and it returns emails that have attachments. It's super useful for finding that document someone sent you. I'd like to be able to do similar in Tana. Perhaps has:image would return nodes that have files of content-type image - with similar filters for other content types. This could be combined with other terms in live queries to answer questions like "find nodes with images that I've tagged as #portfolio" or "find nodes with images or pdfs that I've tagged as #tax".
