All images are posted with too big size and they cause troubles to load the page for people who have bad internet connection and for people who have limits on total bandwidth they subscribe to use with their service providers.
I edited those images with width=200 to decrease their sizes and avoid those problems. You can choose to edit them with width or height but I think width is better because it will not distort images. To save bandwith for others, I posted only one image, for others you can copy and paste width=200.
Using the width property doesn't change the filesize of the image itself. It will have no impact on bandwidth of others. It's still better for them to make those images smaller, though, since that post is annoying to scroll past.
