Adding remote "Product Image" and "Product Gallery" via SQL:
1) enable "FIFU Settings → Metadata → Schedule Metadata Generation";

2020-01-19 | ### WP All Import | plugin

Importing Variable Products to WooCommerce:
1) you should choose one of these options during the import:
- "All my variable products have SKUs or some other unique identifier. Each variation is linked to its parent with its parent's SKU or other unique identifier.";
- "All variations for a particular product have the same title as the parent product."
Options where the parent is created automatically won't work well.
Avoiding updates on unchanged image data:
1) access "WP All Import → Import Settings";
2) select "Update existing posts/products with changed data in your file → Choose which data to update";
3) uncheck "Images" (otherwise WP All Import will delete the image metadata and FIFU will need to create that again);

2019-12-22 | ### Jetpack | plugin

Showing remote images on "Related Posts":
x) there is no local solution. Jetpack Related Posts documentation informs: "we do all the analysis, processing, and serving from our cloud". It means Jetpack would need to adapt its web service to work with the images provided by FIFU. So you may contact Jetpack support, install an alternative plugin for Related Posts, like this, or try this snippet (untested).
