I've downloaded many photos from StockUnlimited under my AppSumo deal as I run workshops and like to include pictures on my slides for the visual learners. For this purpose the images are great.

Generally I find there's a better quality and some different options versus the free alternatives. Versus the other regular AppSumo offer DepositPhotos the photos aren't as good, but I find these deals work well together. I use StockUnlimited as my main option, but if there's an image where I couldn't find what I was looking for, or I need something really special I use a DepositPhotos credit. Otherwise I use StockUnlimited lots. Thanks!
