Putting together a group of pictures into a nice gallery is easy. Even the base setting can give you a great blog post. Add a image plugin and you can really have a great post.
Step 1. Add as many pictures as you like. Keep in mind that even then small thumbnails will take a few extra seconds to load the page.
Step 2. Add the gallary to your post by using the code any where in a page or post that you would like the gallery to appear.
Step 3. Save or Update your page or post.
This particular gallery I have the plugin jQuery Lightbox For Native Galleries installed.
