We had some serious issues with images not being present after upgrading to Mediawiki 1.12 on Wednesday. <br><br><b>1. Images were initially only visible when you were logged in. <br></b><br>This problem was solved yesterday at around 2:00 PM EST. Austin and I looked at the problem. He pointed out that images are not directly rendered statically by the web server but instead go through a php script. This is done to keep images from being distributed to users in the wiki is locked down. If this were not the case, anyone could look at any wiki image, either on public or private wikis. The code to do this changed in 1.12. We reverted back to the old 1.9 release for this file (img_auth.php) and the problem was solved.<br>
<br><b>2. Problems with PNG and TIFF files</b><br><br>Steve Kick identified another image problem I'm working on now. PNG and TIFF images are not working correctly. I'm not sure how widespread the problem is. In MediaWiki, there are typically 2 images: the image and the thumbnail. The thumbnail is rendered once. However, an image can have more than one thumbnail, depending upon the image tag used to display it. I'm looking at this problem now. <br>
<br><br>If anyone sees other image problems, or any problems for that matter, please let me know.<br><br>Once this is settled, Ricardo and I will put together a message describing some of the enhancements in the 1.12 MediaWiki release. In particular, we'll let you know how you can use some of the basic features as well as some of new extensions present. <br>
<br>Now that we're at 1.12, we anticipate being in a position to track MediaWiki releases on a more regular basis. <br><br>Stay tuned for more information.And thanks to Steve and Austin for their comments, help, and contributions. <br>
