Does it also have support for managing scans/photographs? I have about 10 Gbyte of images with respect to a research project about art works. The images also contain scans of materials. I would like to extract facts from these documents and maintain a link between those links and the scans. This means being able to annotate a part of an image, which for example is a text with an illustration or a mentioning of a certain art work.
The same people doing zotero have another project https://tropy.org/ which might be what you're looking for? (Disclaimer: I haven't used tropy personally)
