Note the qualification at the beginning and end of this statement:

Every company I have dealt with thus far has not objected if images from their site/in-game are used for things like fansites, interfaces, signature files (for use on fansites, official forums) etc, providing that:
a) you are only using the graphics for those purposes;
b) you don't try to take credit for creating the images yourself; and
c) you don't make money from their use.

I still need to go digging through Turbines EULA and ToS to see what, if anything, they say, but the chances are they won't have any objection. If you follow what I have above though, you are probably fine.

IANAL* and IANATE** though, so I may be wrong.
