The four common failure causes
Nearly every blank-image import traces to one of these:
Common Scenarios:
- Dead or expired URLs from supplier files that change over time.
- Relative paths like images/1.jpg that Shopify has no domain to resolve against.
- HTTP instead of HTTPS - Shopify may block insecure image sources.
- Files over 20 MB or in unusual formats (SVG, HEIC) that Shopify cannot process.
Audit every URL before the import
ShopTools' image checker validates every URL in your CSV - flags dead links, relative paths and HTTP sources, and can upgrade http:// to https:// automatically.
Features:
- URL validation: Flags dead links and non-image responses
- HTTPS upgrade: Converts http:// image sources to https://
- Alt text check: Reports missing alt attributes at the same time
