Storing image as asset or page resource?

I do a lot of image resizing so static is not the place for my images. I should have mentioned that.

So you are saying page bundle over assets.

Images in assets - nope. Don’t. Only for stuff like watermarking images or processing your favicon or site image.

I’m curious as to why only stuff like watermarking images and processing favicon is suited for assets and why not also content images? Can you please elaborate?
