Replacing all the icons for every single layout ever created for this community is a very time-consuming process. But until then, for those that know how, you can choose the appropriate tiny-icons for your layout, (refer to their image previews), and copy/paste the image codes into the CSS.
Again, this is an extremely time-consuming process, but I will do this for you guys! Until then, just go to that blogspot that I've given you and try to find the icons until I can get all the layouts fixed. Note that not all icons are uploaded to the blogspot, but MOST of them are. Let me know which ones are missing if you can, please.
