I’d stay away from imgur. They’re basically a social media site now, with reputations that go up or down, presumably based on other users’ opinions of you. They’ve also changed the way their albums work-now if you make an album public, you can’t add any new images, and I could find no instructions on how to UNDO making an album public. Their organization style is awful, making it almost impossible to find anything you might actually want. The front page features their “hot” images, which are a mixed bag of political BS, things you might want to see, and vulgar/gross imagery.
A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities allow customers to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for websites that wish to keep the data transmitted more secure.
