Select the image you want to upload from your computer with the 'Browse' button and then hit Upload - give it a couple of seconds. You'll get a message upon success or failure.

Images need to be in JPG format. Max file size is 500kb

The image will be rescaled to 160x160 pixels automatically. Note that when you return to the homepage, you may need to refresh the page to see your new image.

There is only one Reader Spot Pic, so the image will last as long as it takes for somebody else to upload one! Upload what the hell you want - an ad for your site, a picture of your ugly mug, whatever you feel like. You may well try 'shock' pics or porn but that would be kind of unoriginal, so you know - whatever!

This is what you call your social experiment!
