I would like to get FlickrService running correctly under 2.3. So far I have everything running except the popups. The current setup using LightWindow has so many dependencies I have no chance of sorting out the problems so I am starting from scratch using jquery (which I want to learn)
I have a Popup that I think can be extended to work but it fails within Silverstripe because of a conflict between jquery.js and prototype.js.
Is there a simple way to stop prototype.js from being included in the page?
I've posted my FlickrService 'recipe' in a new topic: a recipe for FlickrService on 2.3.1
Your problem with usernames may be something different. I had that happen initially then it started working for me. I'm left to wonder if there was a problem with the API key where it took a day or so before it provided full functionality.
The username, by the way, is the screen name. Our Flickr account has a screen name, a (mostly) numeric ID and another short name that appears in the URL. Its the screen name, which also shows as 'Signed in as...', that you want.
