Yahoo's massive change to Flickr recently rolled out and prompted a flood of criticism from users, dismayed by the wall-to-wall photos and new account plans."With over 18,000 negative comments on the official thread, I imagine we, the users of Flickr, should receive an official response from Flickr stating whether they plan to make adjustments to their plan or stick with the current catastrophe," Flickr user Garrett T. posted in the site's help forum.But it looks like Mr. T may be out of luck. Flickr began responding to users with an official message that reads, in part: "We're sorry to hear that you didn't like the new changes Flickr recently instituted" -- which is not exactly an apology. Further, Flickr also said it will not be reverting back to the prior version of Flickr, as many users have called for.In other words, if you don't like it, you can leave. But where to go? Here are three alternatives to consider.
