guys i wish to start a image hosting website.Can you guys tell me what all legal things to be done to create that type of site?
Copyright issues would be your major concern. You need a clearly stated terms of service that prohibits the uploading of copyrighted & adult content. You'll need to put measures in place to detect and remove these uploads. To fall under Dmca safe harbor protection you also have to register a copyright agent for your site that handles copyright issues.
