Internal Server Error on uploaded images

I have the same error. I am running CKfinder in demo mode, downloaded it today. I am running CKeditor, downloaded it yesterday. So, current versions. When I upload an image, the thumb shows in the file browser, but it shows broken in the preview and the editor. If I go directly to the image url, it shows internal server error 500.

I clicked on your link above, and the image displays. I wonder if mine does for you, because it doesn't for me! http://www.rumblenews.com/project/ckfinder/userfiles/2/images/DW-1390_Wifi.jpg

Well, I'm back at it this morning. I checked on the original poster's image this morning, and now it gives a 500 error -- but it worked last night. Hmmm. Mine is still down. I'm running the site in a Linux apache server. I'm accessing it from an xp machine. I've tried both the latest firefox and latest ie. I'm really hoping that someone can find a fix for this!

FIX: Okay, I've have found the fix. The .htaccess file. If I rename it, error goes away. Images work, hooray. Now, I'm sure that the .htaccess file was there for a reason. It's contents are "php_value engine off" -- I believe that prevents *.php files from running in sub directories (a GOOD thing for security). However, it is breaking the images somehow.

New Question: How can we modify the .htaccess file to keep images working, but to prevent *.php files from being uploaded and run by "hackers"?

The php_value setting works only when PHP is used as an Apache module, so the following value could be used in .htaccess instead, to get rid of HTTP 500 errors in other cases:

<IfModule mod_php5.c>
  php_value engine off
</IfModule>
<IfModule mod_php4.c>
  php_value engine off
</IfModule>
