Typically I will use the WordPress Lightbox 2 plugin to provide a format for images within posts on a WordPress site. Basically this plugin provides an ajax window that images open in and you can scroll between the images with mini arrows to the left and the right side or you can close the image with a close button that appears at the bottom right of the image display. You can also change any of this appearance easily through the various CSS files included with four different default themes with Lightbox 2. While working on a WordPress site earlier tonight I ran into an issue where the lightbox 2 image pop up was falling behind the body content. The fix ended up being easy but it needed to be pointed out for others to fix quickly.
I have used the NextGen Gallery WordPress plugin on a bunch of different projects and have always been satisfied with the functionality. On a recent WordPress project I was working on I installed NextGen Gallery assuming I would use it however after I got a bit further on the project I decided it wasn’t necessary and that it would be easier to simply use the default WordPress media uploading capabilities along with the “Lightbox 2” and the “Flexible Upload D3Z Edition” WordPress plugins instead. While NextGen gallery has tons of functionality and typically is easy to use for this project there would be many authors and I needed the path of least resistance to allow authors to write articles.
