The WordPress default galleries always link to the full image size which can be pretty annyoing because most users upload huge pictures.
With this plugin you can set a default size for the galleries to link to. This can be thumbnail, medium, large or full.
For now this a global setting for all galleries, but on a future version I plan to let you choose a specific size for each gallery you create on your WordPress posts or pages.
It’s also possible to add arguments to the link (A) tag. This may be useful to add lightbox/fancybox script compatibility.

Custom Image Sizes by 99 Robots


This seems like this is the best custom image size plugin freely available today.



The plugin does what one expects/needs it to do without any added complexity. The interface is then neither too basic/unstyled (like some other popular custom image size plugins) nor does it go over the top & make things more complex than it needs to be.



It's also nice to see this plugin is on GitHub where the most recent patch was actually community-provided & officially adopted in the new release (rather than being somewhat stagnant and/or over-relying on the plugin developer to come up with improvements/fixes/etc.) It's also good to see some activity regarding support and updates (again, unlike some other popular plugins for this.)


Worked exactly as expected with a nice interface
