A quick preflight for Shopify CSV image URLs before import

When a Shopify product CSV imports but product photos fail, the problem is often not the CSV syntax. It is usually that Shopify cannot fetch one or more image URLs during import. Here is the preflight I use before retrying a large product upload: Check that every Image Src or Variant Image value starts with http or https. Local paths like C:\images\shirt.jpg will not work. Open a few image URLs in a private browser window. If the image requires a login, expires, redirects to a file-sharing preview page, or blocks hotlinking, Shopify may not be able to download it. Keep image rows grouped with the correct product handle. Sorting a CSV by image column or price can separate continuation image rows from their product. Watch for URLs that do not end in a normal image extension. They can work, but they are worth checking manually before a full import. Test one small batch first, then verify the product admin after Shopify finishes downloading the images. For a larger file, I also like to extract the image columns into a review worksheet before touching product data. I built a small browser-side checker for that workflow here: https://shopify-csv.aivismonitor.com/shopify-csv-image-url-reachability-checker The important part is to fix image reachability before changing product titles, variants, or prices. Otherwise you can spend time debugging the wrong part of the import.
