How do I resize an image?

HOW IN THE WORLD???

I just tried uploading three photos from my phone. Two of them turned out huge and blurry as hell, barely even readable, but the third one looks totally fine!?!😕

just install it then hit ctrl + r 🙂

SORRY, I don't get it. I tried🙂

did you install it yet? just open the image, hit ctrl + r, type in how many pixels you want to shrink it by, and save. easy as that...
