I Updated my Flickr Groups Organiser Greasemonkey script. As well as letting you tag your groups and list your groups by tag, It now lets you browse images and discussions in those tagged groups. Current version = 0.8 - 16th June.
The image browsing functionality was inspired by guu's Group Pool Watch script, but this script now has paging, so you can page through filtered results. The filters available for browsing your tagged groups are: Recent Photos, Earliest Photos, Most Interesting Photos, Least Interesting Photos, Random Photos, Your Pics, Recent Discussions. When browsing by images, if you mouse over a thumnail it replaces the images with a larger version so you can see it more clearly. Theres also a search filter coming too, but its not quite ready yet.
You can get my updated Groups Organiser script here. All my other flickr greasemonkey scripts can be obtained here. If you enjoy using my scripts and appreciate my work, please consider making a donation, so that i can continue my work.
