[ WONDERING ] how to make my images appear in a nicer way

I added some photos to the last post. Have yet to figure out how to order them so they appear nicely. Right now all images are shown in their various sizes, one by one. Would be nice if they did a gallery or something.

Also, just figured out how to add some widgets. Unsure if they can vary in design, but it could be determined by the Theme you use.
