The modified image should be in the path set with $new_image, try modifying your code to this:

Code: Select all

// Uncomment this line to view the image path
// echo "The new image is saved as $new_image<br>";
// Uncomment this line to view the image

exec("C:/ImageMagick/IMconvert $cmd $new_image 2>&1", $array);

C:/ImageMagick/IMconvert C:\Documents and Settings\adam.capps\Local Settings\Temp\php430.tmp ...

Exactly what characters are in the first argument? I suspect it starts off something like:

Code: Select all

C:/ImageMagick/IMconvert C:\Documents and Settings\adam.capps\Local Settings\Temp\php430.tmp ...

I know this because the error message says it tries to read a file called "C:\Documents", then a file called "and", etc.

C:/ImageMagick/IMconvert image.tif -font C:/Windows/Fonts/ARIAL.TTF -fill rgba(0,0,0,0.5) -pointsize 50 -gravity Center -annotate 40x40+0+0 "Watermarked Text" -write image.tif 2>&1 (last part is snipped)

Invalid Parameter - -pointsize
