Bigger Thumbnail Images
I succeeded in having bigger thumbnail images (100px x 100px) using the instruction fro this post (http://forums.appthemes.com/thumbnail-size-34925/
) However, after upgrading to 1.4 it reverted back to 50px x 50x and all effect I made to get it back to bigger thumbnail size had failed. Any hint that is upgrade-proof will be appreciated. And yes, I'm using a child theme.
