In the Logo settings, you will find how to upload a logo to be used for reports and in the Welcome screen of the interface.
There are four options where logos can be uploaded, downloaded and deleted.
Change small logo: Small logo us used in reports, usually in the top left corner. Example; here is where you could use the logo of the constructor or the project.
Alternate small logo: In some reports you may want to include a second logo. The logo of the architectural firm doing the planning etc. This is not used by the built-in reports but can be retrieved when making reports in XF-designer.
Change large logo: This image is shown in the start up window and is used in some reports that have their own front page.
Large logo for print: If this is set, the logo is used in the front pages of reports instead of the large logo. Its quality will not be reduced
