Visual force / JavaScript error: Access to image has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
I am facing CORS error when accessing image by javascript from visualforce page.
I have already tried adding to CORS whitelisting and remote settings too ..
If I use external image link it works but what ever image use from salesforce content version it shows such error even I tried with sfdc cv public image ContentDownloadUrl.
my use case is exporting image as pdf by html2pdf library .

Access to image at 'https://...content.force.com/sfc/dist/version/download/?oid=...&asPdf=false' from origin 'https://....visual.force.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Try adding the image as a static resource in your code for fixing the CORS error.
