I am new to Lightroom "in the cloud" and have somewhat of a problem the community might have a solution for. I have a lot of unwanted images in my library which I would like to delete (seems like iPhoto generated them for the Face detection feature back in the time and I imported ALL my imagery to LR). Filtering by document size does not seem to be an option neither is filtering by dimensions (like "only show images less than 360x360). Any idea on how I could get rid of this kind of files? I do not have access to LR Classic.
