Image sizes in Research Folder?

I’ve just dragged an image from the web into the research folder…and instead of the small image I dragged, it has stretched it to a rather large size.
The original is 300x340, the research one scales with the window instead.
Not. Good.
In fact, it’s incredibly messy.
Is there a way to keep the original size and stop it from scaling up?

Right-click on the image and choose Edit Image to bring up the scaling controls.
