im sorry. i see now that the attachment did not upload correctly. this would describe the issue.
as u can see the 100% width makes tumbnails the size of a vc row instead of using the adressed thumbnail display in the ellement.
Yes, when lazy loading is turned on, all images are full width. Otherwise, it will lead to “jump” effect on loading. Please, send us a link to the page with the problem so we can try to prepare a custom fix for you or disable lazy loading.
