When you install WordPress, a default theme is installed. Of course, you can stick with that one if you want, but that’s no fun. You want to install a theme that reflects who you are and what you do. If you’re an elegant person, your theme should be elegant. If you’re a punk rocker, choose a punk rock theme. You’ve got thousands of options on WordPress.
Let's face it, one of the things we like best about the web is looking at pictures. The site builders here all offer some degree of photo and gallery display. Some, like Gator, Squarespace, and Wix, also offer loads of stock photography for you to use. Some let you touch up images with editing tools such as cropping, brightness, and in some cases even Instagram-like filters. Others, such as Gator, Simvoly, and uKit offer no photo editing at all, aside from resizing and positioning.
