How do I change the logo on my login page, timesheets, invoices, or reports?
Users with the Admin role have the ability to do this in the Admin > Setup > Miscellaneous > Images section. Here you have the option to configure the image you want including the splash page, timesheet preview, invoice, or reporting.
Note the text "Items appearing in light gray text indicate an image of that Type has been defined in the
unanet.properties file, which takes precedence over these images."
If necessary, you can remove this override in Admin > Properties > Unanet > System > Login Screen Image.
