Re: Need a batch image combiner.
If you use a unix-based operating system (like Linux or Mac), you could try using ImageMagick, a image modification tool used from the command line. Used in conjunction with other powerful unix CLI tools like find, it works quite well. ImageMagick is available for windows, too, but I'm not sure how usable it is from the windows command line, considering how weak and useless the windows command line is.
Like this, for example:
you have one set of pictures in your working directory.
Another set of different pictures with same names in a folder named "folder2" inside the working directory
you want the new pictures in to a folder named "new"
Code:
find *.jpg -prune -exec convert {} folder2/{} +append new/{} \;
it uses the "find" command to find the jpg-files and passes their names to the "convert" tool. It combines pictures with same names from working directory and folder2/ in to new pictures where they are side by side.
