Thanks for being a customer, and thanks for the feedback. I'll look into whether we can revive this or not. Were you using it to find your own photos, or photos from the community, or... ?
I've been a Pro user for a long time before Yahoo started to screw things up badly. Flickr is only alive today because of the communities that use it. A lot of bloggers used and still use it to share pictures that are freely licensed (CC-BY-*), you should at least consider to keep those in some form or another or provide the means to redirect the links from the search result.
