Improperly formatted image_link URL

Pinterest received an image_link value but cannot parse it as a valid URL. Error 104 blocks the row from publishing.

Common breaks include relative paths (/img/abc.jpg), missing protocols (www.example.com/abc.jpg), spaces in the URL, unescaped special characters, and image URLs accidentally wrapped in quotes inside a CSV. URLs with multiple http:// or https:// prefixes also fail validation.

1. Verify every image_link starts with https:// (preferred) or http://.
2. URL-encode any spaces or special characters - replace spaces with %20.
3. Strip surrounding quotes that may have leaked from a CSV serializer.
4. Make sure the URL ends in a file extension (.jpg, .png, .webp) or a valid CDN path.
5. Re-upload and confirm error 104 clears.

• Building image URLs by string concatenation and ending up with a double slash that breaks the CDN
• Submitting tracking-pixel URLs that return text/html instead of an image
• Letting Excel auto-correct https:// to a hyperlink that the CSV exporter mangles
