Problem solved. I'll include the following for other's reference.

" will create quotation marks in the iptc data

Or, if you're using PHP and need all characters that may cause issues replaced, look into using the htmlentities command.

Is there a way to embed quotation marks in the IPTC data of a TIFF image? I've been using the following command in a script
convert $image +profile 8bim +comment -profile 8BIMTEXT:$iptc $image
along with a text file of the following format
8BIM#1028="IPTC"
2#0="�"
2#120#Caption="Caption"
2 ...

I'm looking to add IPTC information to a large number of TIFF files using a PHP script, pulling the IPTC information from a MySQL database - is there anyway to do this WITHOUT having to reference an external file? While creating the external file containing the IPTC information is entirely possible ...

-compose modulate -define compose:args=50,100 -composite $ndir/$name

That runs, but doesn't preserve the transparency in the watermark. Also, pardon my bash ignorance, but why the escape characters?

Thanks for the input. I ditched the backquotes, and switched to -thumbnail instead of -resize which seems to be faster. Is there a downside to that? I'm having trouble figuring out how to combine the covert and composite commands however. I tried this, but it doesn't work:
convert $name -thumbnail ...

Is there anyway to optimize this script to be more efficient/faster? Each image takes .45s to 1s to process... I was hoping it would be a bit faster. (3Ghz, 16 core, 32GB of RAM) Thanks for any advice!

Thanks for your help! Got a Windows batch script working great - for reference, the meat of the file is posted below:

With your command line, IM will not resize them but will decompress and recompress the jpgs. I don't know any way to avoid IM processing even to read and write it again, except to write a script to compute the image sizes or what not and skip processing them altogether. But perhaps one of the IM ...

see note about -quality for jpg images at http://www.imagemagick.org/script/command-line-options.php?ImageMagick=07av2vq2of61ilntu6vlshnsr5#quality

Your images are probably getting decompressed and then recompressed if you are resaving them as jpg, so you lose quality. Also the quality may not be ...

Ideally, I'm looking for a way to upsize small images in a folder while leaving images that are larger alone.

Here's what I've come up with (batch file):
%~d1
CD "%~p1"
MD upsized

FOR %%a in (*.jpg) DO (
convert %%a -resize "2400^<" upsized\%%a
)

PAUSE
It successfully upsizes all of the small ...
