If you are supplying the custom branding image files, the following specifications and requirements apply:
Dimensions: 640 x 100 pixels
File Format: JPEG (.jpg) or PNG (.png)
Dimensions: 400 x 280 pixels
File Format: PNG (.png)
Additional requirements: Rounded corners, drop shadow on right and bottom edges, transparent background
Both images are displayed on a white background. For this reason, we suggest you either use a non-white background, or if using a white background we recommend a solid border to help define the shape and achieve a balanced layout.
