There are times I work with groups and much of their online artwork is stored in a WordPress Upload folder.
There’s a few methods to get those images from that path. I like being able to use SiteSucker, but it often downloads the entire site.
The other easy option is to use wget.
Run this command in the path that you wish to save all the files to, and it’ll get everything in the upload path.
wget -r --no-parent http://yoursite.com/wp-content/uploads/
This is a single threaded command and will take a long time, so just be patient while it does its thing.
