Tnx Chuck S.
I found one
and finally I have it working.
Now the "problem" is that I don't know how can have 1 block for "random" and another for "lastest".
I was trying with "inc_features.php" for random and "inc_features2.php" for latests, in diferents phpbox, but only one works.
And at same time, I want know if is possible remove the "frame" of the thumbnail (overlay-roundp.gif). I was trying but any modification simply no shows the thumbnail :S
Any help is apreciated
