Just looking for other developers opinion on content managed galleries.

I have created a simple, small site using HTML & PHP for a client. They are now looking for a simple gallery which they can manage themselves.

The requirements are simple:
Able to remove and add images
The gallery view will have all the thumbnails, which when clicked will use the JQuery lightbox to display a larger image.
When the image is displayed larger (above) a 'PinIt' button will be visible which will share that image to Pinterest.

I was thinking using ZenPhoto - However, it seems on the forums people are having issues with the PinIt button.

Interested in hearing thoughts on this. I guess this post will also be handy for others looking to plugin a simple gallery into an existing (non-CMS) website.

Many thanks
