Installer should not accept logo files that are not images
Someone created a Configuration on the cardshop using a PDF file as source for the logo - it obviously did not work (see screenshot below), but the installer nonetheless accepted it and the user could not know until they downloaded, installed and accessed the hotspot. I suggest either limiting the formats acceptable to .png or .jpg or at the very least change the wording (both on the installer and cardshop to "jpg/png format only".
