It's great to have an easy way of hosting images in my project without having any technical knowledge or experience with it! I'm able just upload photos from anywhere i want (the service lets you do this) but then edit them right next too using their interface which makes things much easier than doing everything by myself before uploading anything into production server;-) The only thing that could make me think twice about buying one would maybe being charged more if your account goes over some limits since they don't provide unlimited storage space like cloudflare does:-).
Just use what works best at first sight! Hosting multiple pictures within single page so people won’t need tons bandwidth downloading all those small files when visiting our blog/website ;)- Using picture carousel instead big list where users will click several options every time - saving lotsa traffic.
