This advice is for anyone asking why images are not syncing to Shopify, Magento or WooCommerce (Wordpress) websites.
You control the upload of images through Retailer. Make sure the images are assigned to the correct stock items in the stock screen,

Once you have images loaded/imported against stock items, they will upload automatically. This is a one-time sync for an image. If you want an image off the website you will need to delete it manually via your website's admin control centre.
If something has happened with a sync where images should have uploaded but didn't, you will need to re-export them.

Webstores will have limits on the number of images, which should be considered when adding images. For example, Shopify has a limit of 250 images per item, and a variant group is considered one item for image counts (main variant contains all images). Check with your webstore if unsure.
