Upload multiple images at once

Is there was a way to upload all of the images I need for my team's guides into ReadMe at once? In previous Markdown-based doc repos, I've seen things like an "attachments" folder, where you can upload all of the things you want to link to in your docs - is there any feature like that in ReadMe? I've also seen the suggestion in this post that we can host our images on a separate site like Imgur, but it would be much more convenient for my team if we were able to keep all of our images on ReadMe.

Thanks in advance!
