That's true, but Flickr's $49.99 yearly fees for their "Pro plan" aren't as bad as what Photobucket did to their customers when they wanted something like $399 per yr. to allow for the continuation of third party hosting.
I have been a paying member of Flickr since 2006. I have over 80K photos stored on their site (at lower res) and for 49.99 a year it is a bargain. I am pretty sure it was 29.99 a year before, but when renewal time comes again I will be renewing. I use it so I can view my photos anywhere on any connected device. I obviously keep all of my photography on hard drives .
