To easily resize your images for your store, please use the free website: https://imageresizer.com/ to resize to the sizes listed above. This site will both resize and optimize the image for web use while maintaining the visual quality of your image. HINT: when creating the filename for your image, at the end put the 1st size number (ex: banner520.jpg). This makes it easier to find the file on your computer.
If you are using a different resizing tool; ALL images must be in JPG format and have a maximum resolution of 72 dpi (dots per inch) which is recommended for websites.
