Photoset Grid is a simple jQuery plugin to arrange images into a flexible grid, based on Tumblr’s photoset feature. Originally the plugin was created for the Style Hatch Tumblr themes as a way to use the photoset grid in responsive layouts, but they have since expanded it and released a jQuery plugin for us.
Beyond the basic usage, you can set a number of optional arguments including callback functions that are useful for adding a lightbox for high resolution images. You can download Photoset Grid jQuery plugin on Github.
