If I can help – mine works under Travelify. Here is the step I took. First I went into my firefox browser and add a firebug so I can see what is the code name – your the rectangular and put it anywhere on your site. Make sure you are under HTML and Style. Then I download Glimp.org which you can resize the picture but make sure you export it as a png. That way it will blend with the background. Then go under your dashboard, Media and download the picture. Copy the URL and past it into a note pad. Then go under WPide/Theme/Travelify/Library/Structure/Header
Then to Ctrl + F which will show on your dashboard – search for site-title –
Replace <?php bloginfo( ‘name’); ?> with <image src=” “/>
Paste your url in between the bracket. If the logo is too big repeat the above and make it smaller. Hope that help.
