Hi, yes it made sense, and thanks for the input. Having multiple-image URL searching isn’t something I plan to implement right now. But if other users also request it I’ll take another look.
I understand your idea about using post title as a key. The plugin doesn’t support that, as you know. But you also don’t have to use post ID either – you can upload any key you like (part #, VIN, etc) to a custom field and search by that.
