Replacing images in DAM to auto-correct on pages
To ensure optimal site performance and user experience, ALL images must be accurately sized within content blocks and other widgets. In addition to precise dimensions, ALL images — whether they are hero or a thumbnail — MUST be optimized to be less than 500KB.
If they are not, there is an efficient way to replace bad images with good ones directly within the DAM. Doing so will automatically change the image on all pages that had been using the original, bad image to the new, correct image.
