Snippet, shortcode type library plugin?

Hi

I have been searching for a snippet type plugin that will display a menu in admin of items an editor can add to their posts or pages.

I have a few images with specific links wrapped around them that I want a client to simply either be able to click to add to the post or page or maybe add a simple shortcode to that post or page where they want the content to appear.

I’ve looked at quite a few snippet type plugins, but none seem to do what I want.

Any help would be much appreciated.

many thanks

Mr M
