Templates and skins in IPB
The Look & Feel tab in the admin panel allows you to fully customize your Invision forum. Skins must be chosen depending on your IPB version number. There are plenty of web sites on the Internet that provide free and paid skins / templates for Invision Power Boards. To name a few:
Invisionize.com
IPBSkinworks.com
Jasidog.com
Invisionize.com is probably the best place you can search for templates, skins, modules, etc.
The installation of a chosen IPB template requires a few steps.


Import ipb_images-listed-images.xml.gz under "Import Skin Images" section and ipb_skin-listed.xml.gz under "Import Skin Templates". File names may vary but the point here is to make sure that you are uploading .xml.* files.
After you are done importing the files, click on Skin Tools -> Rebuild Skin Set Cache to rebuild the cache of the new template.
Go to Skin Manager and select the newly installed skin:
