I have been looking for this for the past year on my evo using cm7. I really wish Flickr would come out and make their own app. This shows how much yahoo is not invested in improving the existing Flickr experience. Most people are satisfied with using low res Facebook, and Flickr has become stagnant from an investors perspective.
Anyway, there are a number of different apps out there that you can view Flickr photos with. There's "just pictures", which acts as a replacement gallery, and you can view Flickr, Facebook, and others. Flicka was the most promising app with a lot of features. It hasnt been updated in a long time, but according to the website it is going through a rewrite, and hopefully will get a lot better.
