Pixlr

“I use a lot of imagery in my slide decks, often sourced from freeimages.com, and I like to use Pixlr to tweak the images a bit - applying filters and lighting effects to take an ordinary stock image and give it my own spin.”

“The most helpful piece of software I've discovered recently is online photo-editing platform Pixlr.”

“For example, my image editing never needs to be too complex, and I move between computers a lot, so Pixlr's web-based image editing tool is great.”
