Export frames of animation separately

I'm working with lots of Photoshop animations provided to me by a designer. Each one is made of six frames, and I need to export each frame so that they have the titles (say): left*.png, where * is 0-5 depending on the frame.

Does anyone know if there's a quick way of doing this? So far I've been doing it by hand, but this is obviously far from ideal considering I have many animations to get through!

Set each frame duration to 1 second. Then go to File > Export > Video render

Select "Images sequence", "All images" and set the frequency to 1 image per second.

Click on Render, and each frame should be exported to an image.

For people looking for exports with a transparent background..

First export all frames to layers:

Timeline panel > Flatten Frames Into Layers

Then Export all layers to files:

File > Export > Layers to files
