Generating Ack Slides


About

NOTE: This page is a daughter page of: JavaScript


I'm a big fan of starting a presentation with an Acknowledgement slides which includes everyone's photo, but making such a slide is pretty slow if you have five or more people. This tool lets you enter the names of people and will either generate a link to their profile photo (most good orgs have this ability) or specify your own image URL for each person's photo.
