Unsplash Images

Unsplash is one of the most popular stock photo websites because it provides a library with millions of free images. They also offer a Google Slides add-on that makes it easy to insert their images directly into a slide deck.
Customers say it’s a great way to find slide backgrounds and high-quality images without leaving Google Slides, but unfortunately, customers report that the add-on often doesn’t work or the images don’t load properly.

Pexels
Pexels is a smaller alternative to Unsplash, and their add-on offers similar functionality to Unsplash. Users report it’s a great way to find images to insert into slide decks without having to leave the Google Slides app. While Unsplash is a better known brand and website, fewer people report issues with the Pexels add-on, so that's a win in our book!

Auto-LaTeX

Auto-LaTeX probably only sounds interesting to people who need to regularly use LaTeX notation, so if that doesn’t make sense to you, then you can just skip this add-on.
For people who need to write mathematical equations, however, this is a great tool that will automatically convert mathematical notation into high quality, LaTeX rendered images in both Google Slides and Google Docs.
Users say they love how the product actually works (compared to competitors) and the fact that it can convert all of the equations in a document at the same time (instead of using other products that can only convert one equation at a time)

Icons for Slides & Docs

Icons for Slides & Docs is an add-on that allows users to search the Flaticon icon database for icons and insert them directly into Google Slides, Docs, and Sheets. Similar to the stock photo add-ons, this makes it more convenient to quickly find the icons you need.
Users report it can be difficult to figure out how to use the add-on, but once they figure it out, it is an easy way to get icons, customize them, and do it all from within Google Slides.
