Slideshow Won't Change Slides

Hello,
Running Joomla 2.5.11 and I believe I have the latest SlideshowCK running and I have the images labeled: 001.jpg, 002.jpg, etc. The module won't change the images. I have 4 slides at roe41.org
Thanks

Hi
please add a text in the images name, not only the numbers like
img001.jpg
CEd

Good morning and thanks for the reply,
I added the img and made the image names: img001.jpg, img002.jpg, img003.jpg, and img004.jpg. They still won't rotate through the sequence. Thanks for the help!

please unpublish this module, create a new one and tell me if it works with the preinstalled data

Hello - did as you instructed and now I get this error message:

Fatal error: Call to undefined function imagecreatefromjpeg() in E:\wamp\www\joomla4\modules\mod_slideshowck\helper.php on line 245

When I switch back to the original Slideshow it will display the first slide of the 4.

Thanks

ok then try to disable the thumbnails option and tell me
