Product image configuration
If you plan to upload large images for viewing on the Product Details page, you may want to consider setting a maximum pixel size (width and height) and automatically resize the files at upload. To support this type of product image upload, there is an option to enable automatic resizing of larger image files as you upload. For product that you want to add to your catalog but you do not yet have an image asset to display, you can configure a placeholder image.
Product image resizing
When uploading product images, you may add larger images with varying sizes to provide detailed, high-quality zooms on the Product Details page. To ensure that all images have a similar size and look, there is an image resizing option to ensure that all images match a specific pixel size. This option automatically resizes all product images using the configuration settings, which can help with performance of zoom, faster loading of images and keep a uniform look to your product images.
sRGB color profile. All other color profiles are automatically converted to the sRGB color profile during the product image upload, which could cause color inconsistency in the uploaded image.Setting a maximum pixel width and height resizes the image to the physical dimensions by pixel. Commerce resizes the image according to the higher amount of either width or height while keeping the proportions. Reducing the quality amount for JPG images reduces the file size.
For example, a 3000 x 2100 pixel JPG at 100% could be a 5 mb or larger image file. Resizing this image would reduce the width to 1920 pixels, keeping proportions, and quality to 80% to provide much smaller file size with high quality.
