how to put avatar on last post

[RateU]

No, no, no. Don't say that. I'm still learning. Even I don't know how much performance reduced by the plugin
It has a different area. The plugin attached in this thread is for lastposter avatar, as what you asked. The plugin linked to MyBB site is for thread author. What I meant is, if you really want to use both of them, I think it is better to reduce the number of threads for each page in your threadlist.
