Optimal logo size is 640 by 100 pixels. If your image is larger, some clipping will occur.
To upload your logo, launch Documents and Templates Manager by clicking Setup button on YAPI toolbar and selecting Manage Documents and Templates command from the drop down menu.
Select Public tab, click Logo button, and select an image from your computer. Once image is uploaded, YAPI will display image thumbnail just below Logo text. If you don’t see your logo click Get button.
