If you want to copy your images from soup.io to WordPress, here is what you should do:
- Download your RSS , you can find the link on Your page > Admin icon > Privacy > Export RSS
- Open RSS file with vim (believe me, it's harder to manipulate with sed, thanks to newlines),
- Parse the file with these substitution commands:
(Removes the body part, which I don't need because I want my images only)
(Removes the "Reposted by:" part)
- Save and exit ( :wq )
- Import the file with Tools > Import > RSS in your WordPress admin panel.
