There's been another case here today where someone has "hotlinked" an image from another site. The image was then replaced by a naughty and extremely obscene picture by the site owners which was then displaying on HotUKDeals.
Hotlinking is basically where you take the URL (web address) of an image that is hosted on another site, such as "http://www.hotukdeals.com/images/alerts_rss.gif" and post it here in a comment/reply. Whilst it takes a very unscroupulous site to do something as harsh as change their links to dirty pictures, it's still considered bad manners to link directly to an image on someone else's site as this uses up their paid-for bandwidth.
So we are, once again, urging all users to use extreme caution when posting images from other sites.
To avoid problems and be polite to other hosts, please upload the image to a site such as the ones in this list:http://www.imageshack.ushttp://www.tinypic.comhttp://www.photobucket.com

This does not affect the images in deal posts as they are automatically re-sized and uploaded to the HUKD server. Obviously, if it's a deal for a TV at Argos and you want to post a reply with a picture of a different TV at Argos or something along those lines then it's not really a worry.
Please post here if you need any help uploading any pictures to an imagehost, or if you have any questions.
