Personal Image Classifier

When I try to add the pictures in a particular label, there is no drag and drop option. I have to manually select one picture after the other, which is very tedious.

Is there a way I could select the entire contents of a folder at once?

Are you saying about Image Picker?

No, I am taking about the image classifier extension.

If it is an extension please give the link to that extension

I am not understanding what you are saying

I mean that when I try to train the image classifier model on picture, I have to manually select one picture and then upload and then again do the same for the rest of the pictures that I want to be a part of the database.
Is there a way I could select all the pictures at once and upload them altogether.

Also, thank you for helping me out.

There is no way to do that without using any extensions aor activity starter.
You may get some idea from here-
