I need a tool to help me merge individual Blender-rendered images into one long image. I have a setup in Blender where an object will rotate 360 degrees while the camera renders images at each angle and saves them as [name]####, where the #### is the current number of the frame such as 0001 or 0360. Now, if I have this setup to only render maybe 32 frames, its manageable to piece them together into a long string manually, but if I wanted to render 360 frames, creating a single image out of them is carpal tunnel waiting to happen.

At one point Theodis made a little program that does this, however, aside from having apparently lost the program, it also linked the images together horizontally, while at the moment I need them to be linked vertically.

Does anyone know of a decent (free) program that can do that?

[Edit] Nevermind, I found one that works just fine for what I need called Photoscape.
