Support choose from images uploaded before

[zeroceus]

Currently there is no path to choose the images that uploaded before.(tinymce_assets#index). Is there any plan on supporting it?

Hi

I don’t really use the library any more, so from my side, it’s not something that’s going to happen any time soon

But if anyone wants to create a pull request, it’s likely it would get merged. It sounds like a useful feature
