It replaced all redirects, not just image link redirects, with a direct link to what the redirect linked to. The biggest issue concerned redirects that pointed to a category as they turned into categories, which removed words from paragraphs and incorrectly categorised a bunch of articles.

It also depopulated the redirect "links to" lists. Not an immediate issue but has an impact if the redirect gets turned into an article or if the redirect is adjusted so you have a situation where two articles on the surface look like they have a link that goes to the same place, but thanks to the bot replacing the link under the surface they now have branched apart.
