If someone else might own the copyright to it, don't upload it. Don't upload gore, "hate speech" (i.e. demeaning race, gender, age, religious or sexual orientation, etc.), or material that is threatening, harassing, defamatory, or that encourages violence or crime
For NSFW (not safe for work) related material please use the "not family safe upload" option during the upload proces.
Don't upload illegal content such as child porn or nonconsensual ("revenge") porn. Don't hotlink to adult content or to file-sharing, gambling, torrent, warez etc. Don't impersonate someone else.
Also, don't use IMGUP to host image libraries you link to from elsewhere, content for your website, advertising, avatars, or anything else that turns us into your content delivery network.
If you do – and we will be the judge – or if you do anything illegal, in addition to any other legal rights we may have, we will ban you along with the site you're hotlinking from, delete all your images, report you to the authorities if necessary, and prevent you from viewing any images hosted on IMGUP.
