A question/suggestion related specifically to VB4:
The forum-style index layout is currently using the class=\"forumicon\" when vb4 style integration is turned on. This class also seems to include the icon size (style var "foumicon_size"), in other words the gallery thumbails are going to match the size of the forum icons. When using a skin with smaller icons, they can turn out very small.
For some reason only the width is inherited though, playing around with some of the comments mentioned above, I had no problem adjusting the height. Removing the reference to the forumicon class gives control over size back, but obviously has some undesired effects.
Would be great if this dependency between forumicons/gallerythumbs for vb4 could be removed in one of the next releases. Thanks.
