How do I quickly find an already uploaded image?

Sometimes I want to use a previously uploaded image in a new blog post. As I have a couple thousand photos on my site, it is impossible to simply use the scroll bar in the image upload dialog to search for the image. Is there any more efficient way to do this?

Wondering this as well - did you find an answer? I’m new to squarespace and have been using Wordpress. In Wordpress I have access to my gallery of photos (that I’ve uploaded) from anywhere in the backend including the blog. Is this maybe not the case in squarespace 7.1 ?
Seems I  have to upload the photo again rather than being able to add from gallery like I would do from other places on the backend.
