When you just want to manage the post thumbnail or featured images, you don’t have that on quick edit option. You have to go to the edit page, change featured image, save and then go to another post edit page and repeat the process.
Now with this plugin, you can do that directly from your “All Posts” page. When you activate the plugin, a new column called thumbnail is added there. From there, you can add, change or remove featured images of your post.

The standard gallery in WordPress has one limitation — it always shows all the pictures in the gallery. I know there are alternative galleries available, which support pagination, but I never thought this is a good approach. The reader never wants to see n-th page of the gallery — if the first page got his attention, then he wants to see all of the rest, not split into pages anymore. At least, this is how I see it.
So, if you run a blog, on which you publish huge galleries with many many many pictures, maybe you want to show only preview of the gallery on archive pages (homepage, categories, archives etc.), so the individual posts are not too long. The gallery-preview then contains a link, which loads the rest of the gallery if the reader wishes so, via Ajax. Well, this plugin brings exactly that, all with standard WordPress gallery.
Single posts are untouched, they still show full galleries, at least for now.
You can reach similar functionality just by creating two galleries and putting the <!–more–> tag in between them — and the archive page shows only the first gallery, while single post shows the whole gallery. But, this plugin has several advantages: it can be set and forget, and then the plugin automatically applies it for every post/gallery published. If the gallery is followed by another text, then this text is still displayed on the archives page. Loading of the rest of gallery is handled by Ajax (with fallback to single-post URL if Ajax fails).
In options, you specify two values: first one threshold — amount of images, if the gallery exceeds this many, it is sliced into a preview. This is the second value, how many images should be shown in a preview. This allows to have 2 different values for that, e.g. 9 images for preview, but 12 images for threshold, which makes some flexibility, that if the gallery is 10 images big, then it is not shortening by jsut one image. Anyway, you can also specify the same values, if you wish.
These two values are specified on three levels: global (per blog), per post and per gallery tag. You can also specify not to slice a gallery in specific post, resp. not to slice a specific gallery.
Plugin supports several lightbox implementations.
