Thanks. From another post I found it appears it doesn't like the spaces. However, the script runs fine! So I'm ignoring this for now. No sense in uninstalling ImageMagick and reinstalling for the fun of it...

So I am copying to a temp directory and sending error to a log. When ti is succesfully resizing and copying the images I get this???

convert.exe: unable to open image `/': Permission denied @ blob.c/OpenBlob/2480.
1 file(s) copied.

So it's me again. Just had some more images pointed out to me that fit the discribed issue that we had over a year ago. I don't know how to fix this. If I can write to a clean directory and have these images come up wrong then how can I fix this? I was thinking of added a delete to it first, but ...

I did try that but it still would not work. The parser was getting confused on the FOR command with all those quotes. I had to use a temp file for the value but I am concerned that it will be over written when running too quickly and the proper value will not be there at the proper time. This is ...

I am starting a new thread because I was asked to. Don't resurrect old threads especially ones 6 years old! See IM examples, Windows Usage http://www.imagemagick.org/Usage/windows/ This was not available when the original discussion was written. I have searched the examples and documentation and ...

Does IM have a temp area it could be holding onto images in?

Could try that. However it does not explain the images that are there. They do not exist on the file system in the first place. Can image magic read the "deleted" images data on the file system? Windows Server 2003 R2.

Now I am really confused. I used a blank folder and reran all the images so they did not have to overwrite and the same images are wrong again! They look nothing like the originals and when I do it as a one off it works just fine! Where could it be getting those images?

These are JPG's. Any clue as to the proper commands to check the JPG header and file modify date? Sadly I am more developer than photographer so I don't know much about image files...

Thanks for the tip on -regards-warnings. I'll give that a shot and see if I can get more info. Do you know where the warnings are stored?

Well none of the images are write protected. IM is not throwing any errors. So my guess is that Im is opening the filename, which changes the dates and is not getting a chance to write to the file. Would IM not produce an error if it was able to open the file and not able to close it?

No. Let's see if I can make this clear. All the images are good images. However in some cases the new resized image is replacing an old image under the same name. On some of these particular images, the modified date is changed but it is still the old image, not the new one. It would read back ok.

What good would reading the image back do? If I checked the modify date it would be correct and I don't know the size because I resize it so what else can I compare that would be unique to a properly saved image verses one that is not?

We resized 80,000 images in 17 hour period. I have no idea which ones of those did not get updated... So this has never occured before? Are there any commands that can check the output image integrity?
