You can detect the welcome screen in a twig file like this:
Code:
{% if (aSurveyInfo.aNavigator.show and aSurveyInfo.include_content == 'firstpage') %}
<!-- Do something in the Welcome page -->
This is the welcome page!
{% endif %}
Upload the welcome logo with the same name as the normal logo except appended with "_welcome". So the two files are something like
myLogo.png and
myLogo_welcome.png.
In nav_bar.twig, replace this line:
Code:
{{ image(aSurveyInfo.options.brandlogofile, aSurveyInfo.name, {"class": "logo img-responsive"}) }}
With something like this:
Code:
{% set logoFilePath = aSurveyInfo.options.brandlogofile %}
{% if (aSurveyInfo.aNavigator.show and aSurveyInfo.include_content == 'firstpage') %}
{% set logoFilePath = aSurveyInfo.options.brandlogofile|replace({'.png': '_welcome.png', '.jpg': '_welcome.jpg'}) %}
{% endif %}
{{ image(logoFilePath, aSurveyInfo.name, {"class": "logo img-responsive"}) }}
