You can upload individual JPG/JPEG, PNG, and GIF files to the media library. You can name media files so they are automatically assigned to products or collections in your catalog once they are uploaded. See Automatically assign images to products and collections for more information.
To upload a single image:
On the Media tab, select the type of media files to upload. Select Products, Collections, or General.
Click Upload.
Select an image to upload.
You can upload only one image at a time. To upload multiple images at once, see Upload multiple media files.
If you select a file with the same name as a file you already uploaded, the new file replaces the existing one.
Click Save.
