In most cases when using .jpg or .png files, the logo should display once you upload the logo file to Mindflash. If you are using an image file that is .gif, you must click "Apply" in order to display the logo in the preview. This will also apply the logo across the relevant pages in Mindflash.
Note: the logo size should be 76px by 272px.
