That's a very image-centric explanation, and I'm not at all sure it makes things any easier.
Conceptually, in the image case, features are "things" in images that ML tools use to perform tasks.
A image with lots of blue it it has a chance that it is of sky.
An image with lots of hard edges might be something human made - a house, a book etc.
Pixels are really a distraction - there are alternative representations of images which don't use pixels at all. Think wavelet based compressed sensing techniques.
