NextGEN Gallery Optimizer improves your site’s page load speed, by preventing NextGEN’s scripts and stylesheets from loading on posts and pages without NextGEN Gallery content.
Additionally…
If you’re using NextGEN v2 (v2.0.0 to v2.1.60), Optimizer also provides you with complete granular control of the scripts and stylesheets that load on posts and pages with NextGEN Gallery content. For a live example of these settings in action, please view the source of Optimizer’s homepage (a NextGEN v2 gallery page with AJAX pagination) in your browser.
If you’re using NextGEN Legacy (v1.6.2 to v1.9.13) or NextCellent Gallery (v1.9.14 to v1.9.31), Optimizer will intelligently fine-tune all your posts and pages with NextGEN Gallery content…
Very impressed at the quality of support of this great NextGen Optimizer. Rare these days. Highly recommended.

After struggling for hours with Ajax pagination in NexGen Gallery, I came across Optimizer. I couldn’t believe how fast Mark sent a reply to the question I asked relating to my issue. Even better – he solved the problem. Plugin is simple to install and very effective. With support this great I’m going to check out Deactivator as well.
