QGIS MapTips - A Look at using HTML - Show a Photo!
Video #86
In this video (under 4 mins), I show you how to change MapTips to use HTML.
I add 2 websites as links in the maptip and then add an image from a URL source.
Hovering over a feature will display a MapTip. MapTips are set to be displayed when the "Show MapTips" option is clicked under the "View" menu.
