Step 1: Adding a Metafield:
Go to this page: https://admin.shopify.com/settings/custom_data/product/metafields
Click on "Add definition."
Add the properties of the new metafield & save
Name: choose your own
Description: describe the purpose of this metafield
Type: Select File, One file
Step 2: Adding a custom image
Create your images and upload them to the product detail page for each product separately or in bulk using the bulk edit feature for multiple products.
Product detail: adding a custom image into the Metafiled
2. Bulk edit: adding a custom image into the Metafiled
Step 3: Sync your products with Feedyio
Once the tasks above are done, go to the Feedyio app, and first synchronize the products (click the "Sync products with Shopify" button)
When you change or add something in your Shopify (f.e. products/collection/metafield..) the changes are not immediately visible in Feedyio.
Feedyio is syncing with your Shopify once per day by default - you can change the interval in Feedyio settings or run the Sync manually if you wan to show the changes in Feedyio immediately.
Step 4: Adding a Metafield into the feed as an attribute
In Feedyio, go to the feed detail page where you want to add your custom images
In feed detail page, at the bottom, click on "Create Attribute"
3. Add these properties and hit save:
Attribute/Field: Custom attribute
Source: Metafield
Metafield key: Select your metafield from the list
Custom attribute name/field:
This value is different for each feedGMC: g:image_link
META: g:image_link
Bing: g:image_link
Favi, Biano: IMGURL
4. Save the feed, and you're all set!
If the metafield is empty, the default Shopify product image will be used instead.
