Plugins to Optimize Your WordPress Photoblog
this plugin provides useful image management features that include edit title and alt text for multiple images on the same screen, create thumbnail images, and exclude certain images from showing up in the gallery without deleting them from the gallery entirely. Another important feature is the ability to create slideshows and easily embed them in your page
this plugin permits users to view larger versions of images without having to leave the current page. It offers fourteen pre-defined themes which enables photobloggers to make the right match to fit the look and feel of their website.
The WordPress Automatic Image Hotlink Protection–
this plugin is designed to stop others from stealing your images. “Hotlinking” increases you server usage, but visitors to the site that is stealing your content may not even know that it’s your content they’re viewing. Some themes like Autofocus have similar features already installed, so I’d only consider this plugin if I choose either Duotone or Nishita.
