One option you may not be aware of though, is to use two plugins combined that run on the LightBox display structure.

Here are 6 images that I have uploaded to demonstrate how this gallery looks on the page, and then we will take a look at what is involved in setting up a gallery such as this.

Personally, I am not a huge fan of the Media Uploader, [I much prefer to use ftp and my own-named image directory] however, for this exercise, I have used what WordPress specifically provides for this task.

So, what did I need to make this simple gallery?

1. Two plugins: Lightbox 2 [basic Lightbox which provides Ligtbox functionality] and Add Lightbox [automatically adds the rel="lightbox[ID-OF-THE-POST]” to images linked in a post. The ID-OF-THE-POST is unique per post so all images per post are grouped in one lightbox set.]

2. A few assorted images – I deliberately chose a mix of varying sizes for this example.

3. 5 minutes of your time.

And that’s it! What could be easier for a simple little gallery?
