In this tutorial we will guide you in changing your osCommerce Store logo, which can be accomplished from the Admin panel section. A company logo can help you add branding to your E-commerce website, allowing visitors to identify and differentiate your store from the many other online eshops.
I am running the latest version of osCommerce at the time this tutorial was written, which is: osCommerce Online Merchant v2.3.3
This can change the look of your website, so you may have to work with the image to make it fit seamlessly. Image files will only be accepted by osCommerce if they have the file extension '.png'. The size of the default oscommerce logo is: 200pixels × 50pixels
