With zoom support, a command to reset zoom could also be though of. And when possible, allow to drag and drop the image:

I really would really appreciate if this could be added. I've purchased Sublime Text 3 and I like it a lot, but this is really lacking.

I use the image feature for the first time right now and immediately miss moving with the mouse (or at least with the arrow keys), too. And zooming would indeed be also useful.

Really unfortunate that I can't pinch to zoom or zoom to fit an image. This makes the image preview feature hard to use with high-definition images.

I just want to vote for this.

Hey y'all just want to bump this as something I'd love to see added for Sublime Text 4
