Mike,
This is actually a good thing that the others are displaying properly, so we just have an issue with the thumbnail creation. But, now that I look a little closer, we are not actually running ImageMagick to create the display image because the size is already the same or smaller than the size required by the album, so MG is just making a copy of the original. So, we may actually still have a problem running ImageMagick.
Do you have access to the server where you can run a command at the prompt? If you do, could you run the following command tell me the output:
Mike,
OK, this is getting us closer. I'm not sure where you got your ImageMagick binaries, but I do know that there have been some problems with ImageMagick around version 6.1.0 on win32.
The later releases seem to work pretty well. You might try upgrading your ImageMagick install, the URL I use for my Win32 environments is:
http://www.imagemagick.org/script/binary-releases.php#windows
Either the dll or static version should be fine.
Give this a try and let's see if that gets you going.
Thanks!
Mark
