Visit the site you want to add to the Top SItes.
Move the mouse pointer over to the " + " button, just left of the address bar.
Touch the trackpad with 3 fingers.
Move the mouse to the "Top Sites" in the Bookmarks dropdown.
The site should be now added to the Top Sites as a tile.
Move the mouse pointer to the top left corner of the tile and pin it.
@dominic23: I may not have been specific enough. I know how to simply add a site to Top Sites, my problem is the thumbnail image of that site is NOT what I want...I want a more current one. Per my original post:
If I have the calendar open and drag the URL to Top Sites I get a thumbnail of the Google login page, which doesn't accurately depict the content.
Also, not using a laptop so don't have a trackpad, but again, it wasn't a problem of adding a site...but rather of changing the thumbnail for an existing site. FWIW, I also tried deleting the site in Top Sites and starting over...but I still get an incorrect thumbnail.
Better example...you have a Top Site thumbnail for Apple.com and it (theoretically) shows an apple.com home page thumbnail displaying an iPhone 4. What do you do to change that to a new thumbnail that depicts "today's" apple.com homepage?
Might be corrupted Top Sites preferences Larry...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
Click Go then move the TopSites.plist file to the Trash.
Then try the Google login page and the Apple homepage in Top Sites.
Thanks, Carolyn...but don't think so. It appears to work for most of the Top Sites thumbnails...just a couple of sites it's not working for. I thought it had something do with sites that required a login, but a couple of those show up fine, so it's not that. I'd rather try a little more before rebuilding the .plist...just don't want to through the hassle of adding all those sites back to Top Sites if not necessary.
