Is there any way to update this plugin?

I have used this plugin for years, and now, I notice that the popup, when clicking on the thumbnails inside a post no longer shows a “full-size” image, but just another thumbnail.

I know it has not been updated in a long time, but it worked fine until just recently. Is there a way to get this plugin up-to-date?

I currently have WP 6.0.3 and bbpress 2.6.9
