My site hosts/sells hundreds of photos. To optimize the loading of each image in the front-end I decided to use CDN. The plugin I’m using for that is W3 Total Cache. My question is; is it supposed to delete the images after they are uploaded? I was hoping CDN would act like an image hosting too so that my hosting wouldn’t have to store the images. Does CDN allow that or it requires retaining a copy of each image in the local server?
Is W3 Total Cache supposed to delete the local files after they are uploaded to CDN?
The CDN doesn’t allow or disallow anything – it doesn’t care what you keep on your server. W3 Total Cache does not remove local images after copying them to the CDN – and nor should it. What would happen if your CDN disappeared, or corrupted, or increased it’s prices? You’d lose all of your image files.
