Image Manipulation is making green and pink thumbnails

Question

Using the coldfusion 8 image manipulation we are getting thumbnails that the colors are all green and pink.  This seems to only affect the thumbnails and not the larger resized images.  See screenshot for example.  Any ideas why this is happening or how to fix it?
The functions being used are ImageWrite and ImageScaleToFit.

Answer 1

<!--- Set some defaults used by each image type, unless you override them --->
<cfparam name="jpgQuality" default=".8" />
<cfparam name="defaultInterpolation" default="bicubic" />
<cfparam name="defaultBackground" default="black" />
<!--- Set values for each image type --->
<cfparam name="thumbMaxWidth" default="" />  <!--- leave blank to allow any width (forced to size by height) --->
<cfparam name="thumbMaxHeight" default="60" /> <!--- leave blank to allow any height (forced to size by width, above) --->
<cfparam name="thumbQuality" default="1" />  <!--- number from 0 - 1, 1 being the best --->
<cfparam name="thumbFixedSize" default="false" />  <!--- you MUST set both MaxWidth & MaxHeight to use FixedSize --->
<cfparam name="thumbBackground" default="#defaultBackground#" />  <!--- color of background if fixed size is used --->
<cfparam name="thumbInterpolation" default="#defaultInterpolation#" />  <!--- Interpolation method used for resizing (HUGE performance hit depending on what is used) --->
<cfparam name="normalMaxWidth" default="476" />
<cfparam name="normalMaxHeight" default="324" />
<cfparam name="normalQuality" default="#jpgQuality#" />
<cfparam name="normalFixedSize" default="true" />
<cfparam name="normalBackground" default="#defaultBackground#" />
<cfparam name="normalInterpolation" default="#defaultInterpolation#" />
<cfparam name="zoomMaxWidth" default="670" />
<cfparam name="zoomMaxHeight" default="380" />
<cfparam name="zoomQuality" default="#jpgQuality#" />
<cfparam name="zoomFixedSize" default="true" />
<cfparam name="zoomBackground" default="#defaultBackground#" />
<cfparam name="zoomInterpolation" default="#defaultInterpolation#" />
<!--- Set values for folder paths and the watermark image --->
<cfparam name="originalFolder" default="path to folder for original images" />
<cfparam name="thumbFolder" default="path to folder for thumbnail images" />
<cfparam name="normalFolder" default="path to folder for large images" />
<cfparam name="zoomFolder" default="path to folder for large resized images" />
<cfparam name="watermarkImage" default="" />
<cfparam name="wmXPosition" default="50" />  <!--- value is a number from 0 - 100, 50 = centered --->
<cfparam name="wmYPosition" default="65" />

<!---One of the images this happened to is attached.  This problem doesn't happen everytime but when it does it is a large group of photos.--->
