Where Do I find how to:
Using Jamroom
After loading your own .png image logo (in your custom/active skin area in the Images tab), reset the cache and icons (under ACP link, system tools) and see if it's changed.
If not, you can also go into your skin's "header.tpl" (in templates tab of your skin) and look for the section under "logo". Wherever it says image= logo.png , or maybe image= 468x60_banner.png , change the image file name only from the current name of the jamroom logo image to the name of the logo image you uploaded (for example mylogo.png) in the several places you find it mentioned in the header template of your chosen skin.
Then hit SAVE changes. Then go back to the skin's templates tab and you'll see a little empty checkbox next to the header.tpl. Put a check in that checkbox and save at bottom- that will activate your change.
Lastly, Reset the Cache and be sure to check the icon option while doing that. Then it should change.
