CS4: Fit Image Problem

Question

Recently had a very bizarre issue that just happened. Not sure why, but it won't go away.
I use the Fit Image script quite a bit. For sizing images that will end up on the blog, batching out files for proofs, etc. I have it written into many of my actions.
Up until a few days ago, if you opened any action that I've recorded and expanded out the Fit Image step, you would see the dimensions (in pixels) that were recorded. Then, I started getting an error message for any action that used Fit Image. The error message was "Javascript code was missing".
I checked my scripts folder and the Fit Image script is there. Nothing has changed. I even used Time Machine to go back a few weeks and see if anything had been deleted. Nothing.
I tried to write a new action using Fit Image and now, instead of the expanded view showing the size in pixels, it's showing in inches! When I manually use Fit Image, the dialog box comes up with pixels ONLY, so why is it that the recorded step is shown in inches?
I've gone so far as to uninstall CS4 and reinstall it. The first thing I did was record an action and I'm getting the same results. Why would this just change and does this mean I have to re-record all my actions that use Fit Image?
Any ideas or insight?

Answer 1

The problem come down to the fact the the way scripts are recorded in actions the full path of the script is recorded. If you un-install CS3 its script directory will be deleted so the script is gone CS4 script is in a different directory.
CS2 and prior recording of the plug-in fit image were recorded as step Fit Image not as a script path step.  These actions should still work for when Photoshop starts up the CS4 Fit Image scripts register as the plug-in Automate>Fit Image.  When these action  are played and the plug-in step Fit Image get played it is looking for the registered Fit Image Plug-in Photoshop should run the CS4 Fit Image Script.
The bug in Fit Image is very minor.  One day I used fit image on a image that was 1080 x 1080 and fit image was set to 1200 x 1200 the resulting image turned out to be 1201 x 1200 one side was one pixel off there were 1200 extra pixels.
Reading the CS3 Fit Image Script I saw this:
     docRatio = docWidth / docHeight; // decimal ratio of original width/height
     // NOTE - ccox - 17 Aug 2004 - I added the rounding by 0.5
     // this should solve reported cases of fit image being off by 1 (always under)
     // NOTE - elr - 3 May 2006 - keep original aspect ratio
     newWidth = width;
     newHeight = ((1.0 * width) / docRatio) + 0.5; // decimal calc
     newHeight = 1 * newHeight; // make integer
     if (newHeight > height) {
          newWidth = 0.5 + docRatio * height; // decimal calc
          newWidth = 1 * newWidth; // make integer
          newHeight = height;
Someone fixed fit image not to be one pixel under.  I thought this fix most likely cause my one over problem so I stuck in some alerts to see the numbers. Looked like the multiply by one to round did not round and I thought the .5 value perhaps would work better if it were .4.  So I changed to code to
     docRatio = docWidth / docHeight; // decimal ratio of original width/height
     // NOTE - ccox - 17 Aug 2004 - I added the rounding by 0.5
     // this should solve reported cases of fit image being off by 1 (always under)
     // rounding by .5 seem to make some sides 1 Px large change to .4 and used math round to round JJMack
     // NOTE - elr - 3 May 2006 - keep original aspect ratio
     newWidth = width;
     newHeight = ((1.0 * width) / docRatio) + 0.4; // decimal calc
     newHeight = Math.round(newHeight); // make integer
     if (newHeight > height) {
          newWidth = 0.4 + docRatio * height; // decimal calc
          newWidth = Math.round(newWidth); // make integer
          newHeight = height;
The name of my script file is "My Fit Image.jsx" I renamed Adobe file to "Fit Image.jsx.Adobe" My script is in My Photoshop Script tree which I linked to Photoshop's Presets\Script\ by placing a shortcut to my tree into into Photoshop's Script directory. "My Fit Image.jsx" registers itself as Automate>Fit Image...
