The featured image
The featured post image is the main image for your product. It is the image which will be displayed within your product loops (IE on product categories, up sells, related products etc) and the initial focus of the image gallery on your product details page.
Adding product galleries
Product galleries simply display all images attached to a product, with the Featured Image being the primary image. To create a product gallery just attach the images you want to appear in the gallery to the product. The easiest was to achieve this is to simply click the Upload/Insert icon on the Add New Product screen and drag your images to the upload box.

Image dimension settings
On the catalog tab of the WooCommerce settings you’ll see three image dimension inputs.
- Catalog Images appear on your shop loops. Product categories, up sells / cross sells etc
- Single Product Image is the main image on your product details page
- Product thumbnails are the gallery thumbnails on your product details page (if you have a gallery)
The images you upload will be resized to match the values your input here accurately as possible. IE if your settings are 100×100 and you upload a 300×600 image it will be resized to 100×200. You can also choose to ‘hard crop’ your images which will force them to be the size specified in these settings, regardless of the raw image you upload, but will be cropped rather than distorted in scale.
Remember if you change these settings after uploading product imagery you will need to regenerate your thumbnails within WordPress for the changes to be applied to your current imagery. To do this we recommend using the Regenerate Thumbnails plugin.
