Hi ahanford,
I hope I understand the target correctly, each new frame has a new image (material), or each new multi-frame animation has a new image (takes)?
The simplest way would be an image sequence as texture. Which requires a renaming of each file to have a sequence. Each new design is a single image.
The animation tab of the texture should be set to Exact Frame.
More complex but perhaps easier to manage is the MoGraph Multi-shader; here, a complete folder of images can be load in. If a specific image needs to be changed, access is easy.
If that is not the one you are looking for, then it is Takes

The output to high-resolution images is based on the Render Settings> Output.

Let me know if that answers your question.
