Shutter Reloaded is an image viewer for your website that works similarly to Lightbox, Thickbox, etc. but is under 10KB in size and does not require any external libraries. It has many features: resizing large images if the window is too small to display them with option to show the full size image, combining images in sets, redrawing the window after resizing, pre-loading of neighbour images for faster display and very good browser compatibility.
This plugin offers customization of the colour and opacity settings for the background and colour for the caption text, buttons text and the menu background.
There are options to enable it for all links pointing to an image on your site (with option to exclude some pages), or just on selected pages. It can be enabled only for image links with CS…

Don’t work since 4.4.2 but ok with earlier versions.
Also no support on the forum for this pluggin
What more could you want?
The only caveat is that, for some reason, the background didn’t darken at first. I futzed with it a bit and now it works like a charm. I don’t know what happened, probably because I don’t know what I’m doing. With great plugins like this, I don’t need to. Thank you!
