Changing the image size in Rich Text Editor

Prismic for Content Creators
1

Hi All,

I've been using Prismic on a number of projects but have only recently come across the problem of not been able to resize the image when its added into the RTE.

Is this possible to do as my client is uploading large photos and then wanting to resize them as dont want to load a 3000x3000 photo.

Thanks in advance.
Tom
