text: 1. Create product images of the size not less than 1024 x
  1024px.
  2. Give the correct names to the product images.
  3. Upload the product images to the correct directory on the Web
  server.
  4. Link the images to the products, by running the Product
  image import task.
  5. Check that the product images are shown in the web store.
  Sana can also use product images directly from the ERP system,
  if ERP supports this. Currently, Sana does not support product
  images from SAP Business One and Microsoft Dynamics GP. Thus, you
  can add product images to the file system of Sana.
  For more information about product images in ERP, see:
  Step 1: You must create one image for
  each product and product variant. All images must be of
  a size not less than: width - 1024 px and height
  - 1024 px.
  Step 2: Give the correct names to the images.
  The image file name format must be exactly as described
  below:
  [Item No] [Separator] [Variant Code] [Separator] [Order
  number].[Extension]
  The examples of the product image
  file names:
  Step 3: When the images (not less
  than 1024 x 1024) for each product and product
  variant are ready with the correct file names, they must
  be uploaded to the Web server. All product images must
  be added to the following location of the Sana Commerce
  frontend directory:
  /content/files/images/ProductImages
  Step 4: Now you must run
  the Product image import task to resize
  the images and link them to the products. In Sana
  Admin click: Tools > Scheduled
  tasks, and run the Product image
  import task.
  For more information, see 'Product Image
  Import'.
  When the Product image import task is
  finished you should see the product images in your web store. Open
  the web store and check that the product images are shown. The
  product images must be also shown on the product pages in Sana
  Admin.
  If you need to replace the existing product image, you must put
  the new image with the correct product image file name to the
  "ProductImages" folder, and run the "Product image import" task.
  The image will be resized and will replace the appropriate
  image with the same name in the "Small", "Medium" and "Large"
  folders.
  Product images can be also added directly,
  three folders will be automatically created in the Sana Commerce
  frontend directory on the Web server
  (/content/files/images/ProductImages/): "Small", "Medium" and
  "Large". The Product image import task
  automatically resizes all your product images from the
  "ProductImages" folder and puts them according to the size to the
  "Small", "Medium" and "Large" folders. This is done because product
  images of three different sizes are used in the Sana web store:
  The product images are automatically resized to the sizes which
  do not exceed:
  Therefore, when you prepare the product images, you must create
  only one image of a large size (can be any size not less than 1024
  x 1024px) for every single product and product variant. The images
  should be square-shaped, since they fit the web store design well.
  When the images are ready, size, the images in the "ProductImages"
  folder will be automatically deleted, if the Product image
  import task has been successfully finished.
  In case the image size is larger than 1024 x 1024px, Sana
  downscales the image size to 1024 x 1024px and puts the resized
  image to the "Large" folder. Then Sana creates medium and small
  images and puts them to the relevant folders.
  If you create an image of the size less than 1024 x 1024px, the
  large image will not be available. Sana will downscale the size of
  an image to 400 x 400px and put it to the "Medium" folder. Then,
  Sana will create a small image and put it to the "Small"
  folder.
  The same logic is used, if you create an image smaller than 400
  x 400px. The large and medium images will not be created. Sana will
  downscale the size of an image to 84 x 84px and put it to the
  "Small" folder.
  If you create the image which is not square-shaped, and its
  longer side is more than 1024px, then Sana will downscale the image
  by the longest side, keeping its proportions.
  If you redesign your web store,", or "large", or any new image size
  name, if you customize the web store design), width and height of
  the images:
  <size name="name" width="" height="">
