How can I check whether a link in the file is a valid image link before import, so that only correct and existing paths are imported?

To import an image only when the field in the file contains a valid link, add the appropriate regular expression in the advanced settings for the matched image field, and check that the value should be imported only when it matches the entered expression:




Expression to paste:
/(http|ftp)?s?:?(\/\/[^"']*\.(?:png|jpg|jpeg|gif|png|svg))/
