Scale images

No, this plugin concentrates on lossless image optimizations, and does no resizing. You can take advantage of the resize versions that wordpress generates, or even use the image editing capability in wordpress to resize/scale the images you are serving.

Thank you for answering my question. I have another- I ran the EWWW Image Optimizer and it worked great. Since I also want to scale a number of images, I got the Imsanity plugin but it did not work and instead shows broken links to images. The Imsanity plugin author is helping me troubleshoot this, and said that if at some point another plugin moved image files without updating the WordPress metadata for them, that might cause them to get re-located to where WordPress thinks they should be and some pages may be stuck with an old image URL. Do you think this is what happened when I ran EWWW? Imsanity uses the WordPress meta data to locate image files, not what is on the file system. Please let me know what you think.

EWWW also uses the wordpress metadata to locate files, so it is unlikely. Even more so if you did not turn on any of the ‘conversion’ options, like gif2png. The filepaths are never changed during optimization. If you had enabled any of the conversion options, it is still unlikely, but might be feasible, although EWWW still updates the metadata, and even does a search and replace throughout the whole posts table in the database for links to the image.
