 * Sorry for my late asnswer.
    Yes, i confirm the same sitiation. The blogs with
   2.8.4 version store the images with UPPER extensions, if they are created with
   an image editor who doesen’t convert them in lower extension. I use YAPB for 
   a photo blog, so this plugin do this ( the transformation ).

 * Yes, if you look with ftp in upload directory, you will see that images have 
   UPPERCASE extensions but in “Link image” field have lowercase extensions. The
   2.7.1 version convert them into lowercase extension.

 * 1. Shane G., why to give the write permission to the World at upload folder?
   
   2. I reinstalled the blog with problem ( 2.8 ) using now 2.7.1 . No problem at
   all now. The uploading works very fine, the extension is lowercase. I only regret
   the time lost trying to find the solution at 2.8.

 * In 2.7 version the images with uppercase (.JPG ) extenssion are converted in .
   jpg ( lowercase ) in image manager.
 * I have 5 blogs who have 2.7 version. All those blogs work fine.
 * After i upgrade one blog to 2.8, this problem appeared.
 * I deactivated all the plugins and verified again. The same result.

 * The problem is not at the plugins.
 * The problem is at media uploader. In the past it convert extension of the file
   from UPPER to lower case. Now, at LINK URL is UPPERCASE. It’s ok if i multi rename
   the files with Total Commander. But i don’t want to stay all the time to do this
   at my images.
