Loading Retina Display Image from Flickr (Using Three20 TTThumbnailViewController)

I'm currently using three20's thumbnail view to load images from flickr, the only problem is that they're coming back pixelated. Does anyone know what I could do to fit in an image scale so it looks decent?

Solution

Take a look at your image URL, Flickr offers different image size with suffixes, you can find them in Flickr API documentation: https://secure.flickr.com/services/api/misc.urls.html
