The latest version of Flickr has been optimized for iOS 8 and Apple's Retina displays. The app can display photos in high resolution — up to 3 million pixels per image, according to Flickr.
"No matter the context of your photo adventures — whether you’re socializing with friends, trekking through a market in a faraway city or capturing the most important memories at a family wedding — you’ll never lose a pixel of the full resolution, uncompressed photos in your Flickr account," the company wrote in a blog post. "And with the 1,000GB of free storage, you can upload all your photos not just your favorites!"
