Some external tooling would be fine for me. In theory, I'd like to write something like "createBanner icon=address-book text=Contact" to get a banner image with the correct format, having a little icon in the front and the specified text next to it. One can mess up the template so easily, maybe not everyone can open the file (.psd right now?), or it might look different. Maybe we can look into Inkscape (and it's command line features) for that task. Since an SVG is just a text file, it should be fairly easy to replace some placeholder text with the final words we want to put it. However, this is not a huge deal, and we can live with whatever approach you are taking right now!
