How can I crop an image? Texture/photo.

I’m just starting in UE4, so forgive the question if it’s too easy.
I drag an image I like into UE4. It shows up on the Content Browser.
I drag that onto an object in my scene. A box. It converts it to a Material. I can see the ball shape.

If I double click on either the Texture, or the Material, I can see the image of the 2 dogs I dragged in.
I want to crop out one dog, and I want to make sure the proportions stay as they should be, and not stretch to fit the box, they will be attached to.
I just want to create a simple room, with a photo on the wall, but I want the photo frame to stay the shape I have it, not adjust the frame to stretch the photo to the proper shape.
Any ideas?

It is possible with UVs, but I think it’s easier to fix the image before you import it.

Truer words have never been spoken.

Trying to get Filmora and Unreal to work together is like trying to get a cat to wear knitted booties. I had to get better at video editing to be able to use videos in Unreal’s UI.

What a nightmare it was at first. Aspect ratios can go straight to hell.
