[Review] Keep Screenshots Out of Your iCloud Photo Stream!
The idea behind this tweak is very simple...
The iCloud Photo Stream is the part of iCloud that lets you take photographs (screenshots included) and have them saved to a server on the internet that distributes the photographs to all of your devices instantaneously. Some people really hate the fact that iCloud takes every single photograph you take and stores it on an online server and it further disturbs them that there is no way to delete individual photos without deleting every single one.
At least, you have the power to keep certain photographs from ever seeing iCloud. With this free tweak by Evan Coleman
dubbed Screenshot Dam, you can keep all of your screenshots from going into the iCloud Photo Stream. It's not a flaw-proof tweak; it doesn't give you the ability to pick and choose what goes into Photo Stream, but it will help you keep screenshots out. No applications are added to your home screen and there are no settings to configure. As soon as you install this, it will keep screenshots from being uploaded to the iCloud Photo Stream. To resume uploading screenshots, you can uninstall Screenshot Dam.
