AFAIR the only setting that the LOGO skin object has is for BorderWidth,the alt text for the logo image is automatically extracted from the portalname. Unless you're happy to set that to an empty string, you'll have to amend logo.ascx.vb in Website\admin\Skins . The line would be changed like this

imgLogo.AlternateText = PortalSettings.PortalName

to

imgLogo.AlternateText = String.Empty

ah, sorry i didn't realise you meant the title attribute, not the alt tag. The asp:image tag does not support a title property but you can code it by using the attributes collection i.e

imgLogo.attributes.add("title","some text")
