Just recently i've been trying to put together a folder on my computer as a reference for portrait poses and what not as a library for ideas when i'm out shooting, however Flickr doesn't want it to be easy for you to lift images off their pages and if you've ever tried it you'll know that they place an image called "spaceball.gif" over the top of the images on the overview page... However today I discovered a handy little workaround for this annoyance.

I use firefox for most of my web browsing and have the "AdBlock Plus" plugin, this plugin lets you block ads and anything you want from appearing on your pages (I think you can also get it for Safari, no idea about IE), What I found is that if you add the "spaceball.gif" image to the adblock filter you can then happily drag n drop images straight from the flickr overview page onto your computer

Easy as that.
