Recently Fleace users have been stymied in their attempts to fetch new wallpapers by an error message:
"Could not connect to Flickr: HTTP/1.1 302 Found".
Web developers will immediately recognise that as a redirection response. The library used by Fleace is hard-coded to fetch photo data from http://flickr.com/ , and at some point in the last month Flickr set that address to redirect to http://www.flickr.com/. For most programs this would not be a problem. Browsers do redirections all the time without user intervention. However, Fleace's library had automatic redirections turned off. This has been fixed in Fleace v0.3, which is now available for download. Also, at some point since the Flickr API was first released their base URLs changed to http://api.flickr.com/, so I also switched to that.
Although this was a simple fix it took a while to complete because I did not have a Delphi development environment installed. Fleace was built in Delphi 2005, but for this fix I used the free Turbo Delphi (aka Delphi 2006) in a VirtualBox. I didn't want to put it on my main OS because it has a large collection of software prerequisites, such as the ancient .Net Framework 1.1 (current version is 3.5), that are otherwise unwanted. That worked well, and may lead to further Fleace upgrades in the future.
