This isn't anything new to me, i've been using this program for a good while now and it's proven itself to be useful on many occasions.
It's basically an extremely quick way of taking screenshots. You can chose what area of the screen to take a shot of, or select which application to take a shot of. It then automatically uploads it to the localhostr file hosting service and displays all of the recent images that you have uploaded. It also works with uploading files too, you just drag the file onto the program and it will automatically upload it for you and display the link in the history when it's done.
It also adds a shell extention to windows, so you can just right click on the file that you want to upload, hover over 'Send To' and then click Localhostr Uploadr and it will upload for you without any messing around.
It's an extremely good program and you should check it out if you take screenshots quite a lot, as I do.
