I'll start:

On Baidu Xiangce (Chinese Tumblr), we have: http://xiangce.baidu.com/picture/album/list/3c71a23c6a64dafee634acd48f1747dfe6d32e0c

Cool.  Well, as I started to mention in your first thread, I try to stay away from loading down with too many tumblrs and blogs and such... it would be overwhelmingly non-ending!!!    I love keeping up on the tweets of Mark (markgatiss), Sue (suevertue), Arwel (arwelwjones), Danny (Hargreaves, their fx guy- dannysfx), Louis (louisebrealey)... just for neat thoughts and sherlock-related fun from the source... I know there's several others, including Lara and Amanda and the feeds of various fandom-known sites/groups, but was getting too many to keep up with.  Sherlockology and Cumberbatchweb (http://www.benedictcumberbatch.co.uk) are nice for the main headlines and some pics (and hear about a lot of the rest just thanks to this place!).
As far as pics and reading, I enjoyed http://grummelmaedchen.wordpress.com for her recaps and news bits, and http://sherlock--confessions.tumblr.com is just some silly fun sharing in sentiments about our favorite show.
