Many people love Flickr, but that doesn’t mean it is perfect. There are a lot of little things that Flickr could do better – and thankfully with a tool like the Greasemonkey extension for Firefox, you can put in what the Flickr developers might have left out.

Here are five of the best Flickr Greasemonkey scripts on the Web today.

1. Flickr Image Unblocker – This script gets rid of that annoying image that hovers over an image to keep you from saving it. It remove the “spaceball.gif” blocking and does so very well.

2. Multi Group Sender – This script enables you to easily send your Flickr images to multiple groups at the same time. It works by overriding the normal “Send To Group” button on your Flickr photo page.

3. Flickr EXIF Decorator – Hover over a photo on Flickr to get an unobtrusive translucent overlay in the top left corner showing meta data including camera model, aperture and shutter speed.

4. Flickr Shades – Changes colors of all Flickr pages pages to white text on a black background. You can also easily edit the colors in the script to whatever your preference is.

5. Flickr Photo Magnifier – Have a look at the notes on the images. Basically, when you toggle the magnifier on, you have a small rectangular magnifier on the medium sized image to look at the details. Great for seeing details in photos.
