So this isue isn’t with the Sublime apps themselves but rather about the Sublime News/Blog.
Specifically, images aren’t loading because the URLs in the <img> tags are relative (in the sense that they are lacking the domain) rather than fully qualified.
To be fair, I’m not 100% sure if this is against the RSS spec, but at the very least it breaks images if posts are viewed in two RSS Readers I’ve tried (FeedReader and Akregator – the former works only if you tell it to cache images), as well as if they are passed through a web-service such as Google’s FeedBurner.
I’d appreciate it if you could make this quick fix, as I just went to add the feed upon finding out that Sublime Merge had been released and realizing I wouldn’t have known had I not visited your site.
