We always like an app that makes life that little bit easier. MyPhotostream is a simple thing: it pretty much just displays your iCloud Photo Stream, so photos taken on your iOS devices pop up there shortly after being taken. Usually, seeing your Photo Stream pictures means launching iPhoto, and with big libraries on older Macs, that can be kind of a hassle. MyPhotostream lets you get at those photos much more quickly.
Can it really be that we're at the end of 2013 and Yahoo-owned Flickr is only now getting around to allowing users to embed their photos into websites? That appears to be the case, but better late than never.
Many people use the Flickr photo sharing service as an alternative to the MobileMe "Gallery" feature. Unfortunately, the screen saver preference lacks the option to create a screen saver from Flickr. Sure, you could download and deal with plug-ins, but what if you want to use the default photo screen saver options in Mac OS X? This can be done with a little ingenuity and a great RSS-conversion tool.
