mmm - guessing...

If it's in the image helper, it's probably trying a getThumbnail, which means it's trying to resize an image. If it can't read the image size correctly using getImageSize(), then it will return zero. When it then tries to perform a calculation to figure out how to resize the image - blurgh. (that's tech speak for "division by zero").

Check your images exist and can be accessed by the webserver.

Also, try creating a really simple page that performs the getImageSize function on an image and see if that works or dies. You appear to have gd library installed, that shouldn't be an issue...

in concrete/helpers/image.php
line 29
add .... error_reporting(0);

not the best way i guess but it suppresses the warning.

This seems to only affect windows, i might be clutching at straws here but i think it is the way IIS handles decimal places.
