@Tupka217 - Nope! Vignette is backwards-compatible with the URL formats of the legacy thumbnailer, and all traffic going to the old domains is now forwarded to the new domains, so there should be no change required to places where URLs are embedded in pages. If these are broken, it's probably a bug :)
