Recommendation for the simplest photo' gallery?

[jimford]

I'm running GS CMS off a memory stick on my DD-WRT router, using Optware. I've tried I81N gallery but it brings the router to its knees with 100% CPU use.

I'm looking for a basic gallery plugin that will just show thumbnails that open when clicked, with no fancy CPU hogging effects.

There are 26 gallery plugins available. To save me testing them all, can anyone make any recommendations, please?
