To avoid any loss of quality when loading your logo (eg deformation or graphic defect on the final rendering), we ask that you provide us with an image respecting the following resolution: 230*90 pixels. If this size is respected, we will not make any changes to the source file: the image will then be available in the exact rendering that you send us.
Also remember to provide us with an image with a transparent background (in PNG format), so that the rendering is optimal, regardless of the background color of your platform.
