First, congratulations on the move to the new server. The new address is more elegant, ‘international’ and shorter (easy to remember). It’s a sign we are growing to a very serious project, with a dedicated domain and everything.
Now, about the issues with the icons (to be expected in the first days after such a move):
I don’t have that problem in Chrome (v4.0.288.1), nor the issue with the desktop shortcut reported by Boulie (I have WinXP.SP2).
For me, in the Chronicles layout, only the WinXP icon seems to lack transparency (though I see it with black background i/o white). And that only for the posts before the move to the new server.
If I switch to subSilver however, almost all buttons and icons fail to load correctly:
Another issue is on the Statistics page. The OS & Browser icons section receive doubled icons for the OS/Browsers used on the new server. I don’t know if we can merge them with the old ones, or perhaps the old stats should be just deleted in that section. If neither of the two is possible, perhaps we can find newer, more stylised versions of the duped icons, to use for the stats on the new server. And if you’ll work on those icons, perhaps you can also add the Safari one. See my post here (the SRWare Icon is not so important, though if not added, the members using Iron should be identified as Chrome users i/o Mozilla).
