Hi Arnab,
I just tried as b-rad has suggested which may help you :
Steps:
1. Clone "Stock Header" widget.
2. Make changes as described in step 4 & 5.
3. Goto your portal Themes and update "Header" field value with newly created widget (clone of stock header).
4.- Add below server script where you need to query and assign image URL :
var company_id = gs.getUser().getCompanyID();
//var grGetCompanyLogo = new GlideRecord('table_name');
data.company_logo_url = 'image URL'; // when you get image path
if(data.company_logo_url =='')
data.company_logo_url = false; // When you don't get dynamic image path
5. Update below HTML :
<a class="navbar-brand" ng-if="::!portal.logo && !data.company_logo_url" href="?id={{::portal.homepage_dv}}"><span>{{::portal.title}}</span></a>
<a class="navbar-brand navbar-brand-logo" ng-if="::portal.logo && !data.company_logo_url" href="?id={{::portal.homepage_dv}}">
<img ng-src="{{::portal.logo}}" />
</a>
<a class="navbar-brand" ng-if="!data.company_logo_url" href="?id={{c.data.portal_home_url}}"><span>{{c.data.portal_title}}</span></a>
<a class="navbar-brand navbar-brand-logo" ng-if="data.company_logo_url" href="?id={{c.data.portal_home_url}}">
<img ng-src="{{c.data.company_logo_url}}" />
</a>
Here we are checking :
if the custom company logo url is set/present then show custom logo else show portal logo (just in-case when image URL is blank) you may change as per your requirement.
