Currently, the logo and favicon URLs are full URLs that lead to an offsite path (they're hosted elsewhere), which means that a TLS handshake must be performed every time I log on. However, I want these to have an URL in the XF root, if possible. How would I go about doing this? Do I have to download them, somehow change the address and then re-upload to the root directory? Must I re-adjust the size again? Please walk me through this.
