I've tried following someone's suggestion (@IRB?) to upload images/files direct from my PC (using the appropriate button "Upload a File"). My Adobe "flash" plugin then crashes (Firefox has notable "issues" with flash). Is this a Firefox problem or a "too clever for your own good cause you're using Linux" problem? OR IS IT YOUR FAULT?
Best way to post images here (and the method I always use) is to upload them from your PC to imgur: http://imgur.com/ You can then take the link they generate and paste it here, with image tags either side
