I'm really quite new to QGIS, I want to style polygons fill with raster imagws based on a attribute contained in the property table.
What do I have to write in the description in order to get for each polygon the appropriate raster image?
I'm still confident that the issue is the file path in attribute 'icon' (seeing as this method has worked on a data-set my end). Could you post an example string from this attribute so we can see if it should work? If this is the issue, or if you are having trouble editing this attribute, as you say above, I would recommend re-creating the attribute using concat.
