You could also make the site a lot more friendly and faster loading by resizing your images before uploading them. For example, on th "About Me" page, the first image is displayed at 369x204, but the actual image size is 2101x1081 which means that when someone visits that page they have to wait while each of the enormous images (the second is 1308x1852) is downloaded, and yet, as soon as the image arrives, their browser has to resize it.
If you want an image to display at a certain size, it's much better to reduce it locally then upload the reduced image for display. That way the visitor only need to download the reduced image (which is what they'll eventually see anyway), and the whole page will load much quicker.
