Sorry for the poor translation.
You may have noticed that some templates have site icons but some do not. If you want to add site icons, there are three things to do,
Alternatively, you can add site icons by adding HTML code to layout. master. You can also use falsh. The sitelogon control is simple.
1: copy the sitelogo control to the layout. master file.
<Portal: sitelogo id = "sitelogo" runat = "server"/>
2: using the above control, you can select the icon image from the/data/sites/[siteid]/logos folder and put your icon file in this folder.
Then select in site settings.
3: If no icon is found in the site settings, modify the style.css file and find the following line:
. Logolist {display: none;} Delete or comment out
In addition:
Set site icon hyperlink: overrideurl = "/Path-To-PageYouWant.aspx"
Set the connection text of the site icon: overridetitle = "the title you want"
