I'm looking for some software that can batch process images to remove any identifying features (the same effect as saving a screen shot of the image). I don't want any data associated with the image to remain so that it appears to be a new image to search engines. Is there a program that can do that?
If you're wanting to batch this for other image files you can use imagemagick to remove exif data by using:
convert <input file> -strip <output file>
Per the source it says:
strip the image of any profiles, comments or these PNG chunks: bKGD,cHRM,EXIF,gAMA,iCCP,iTXt,sRGB,tEXt,zCCP,zTXt,date.
If your images are for web or digital usage (I mean RGB 72dpi) you can use Photoshop "save for web" with the option "Metadata: None". It will produce a simple image with no data added (this is to optimize the size).
You can make a batch and save in this way thousands of images automatically.
This will not work if you need CMYK or images that are bigger than a certain size ("save for web" will still work for images up to 5000x5000 pixels), unless you make a second batch to re-save in CMYK 300 dpi or whatever you need. But it is not recommended.
