I'd like to auto-generate images, or rather image sizes, in old posts where the size is currently missing.
Specifically I'm hoping to generate sizes on the fly when a specific (old) image size is missing, but the original image is still in tact.
Background: A while back I cleaned house with images on a site in hopes of normalizing my image sizes. Totally forgetting about the various older auto-generated images that were soft-cropped. So now there are a couple hundred old images that aren't displaying.
Details: I did regenerate all the sizes when the house cleaning took place.
