Hotlinked Image Caching
Here's how this plugin works:
- Enter the post id for the post you need to perform image cache on.
- If you need to perform image cache on all post, then put all in the post id field.
- Then you'll be presented with a list of domains, check the domains you want to grab the image from.
- The images will be copied to your upload directory (this directory is under your hot-linked-image-cacher plugin directory and must be writable).
- The img links in your posts will be updated to their new local url location automatically.
