http://community.wikia.com/wiki/User_blog:Rappy_4187/Technical_Update:_March_10,_2015 Last week the Recent Photos module in the right rail was removed. We apologize for the failure to note this in last week's technical update.

http://community.wikia.com/wiki/User_blog:Kirkburn/Technical_Update:_March_3,_2015 At this time, there are no plans to restore the right rail Photos module ahead of further changes to the right rail, and even then its presence (or the presence of something similar) in the rail is not assured.

See the March 3 post for a lot of discussion about it.

I also started a thread about it, and apparently not many people actually miss it.
