I'm trying to export an animation as a series of bmps, but each bmp is completely fubared. Here are some screenshots.

First up is what happens when I just hit the render button and render the frame I'm currently looking at.

This second image is what happens when I try and export the animation as a series of images (this image is one frame)

Render dimensions

Finally, 'make movie' settings

(click on the image to see it full-size)

Someone else will probably chime in here with an "I know exactly what this is", I don't know, but here's my guess...

Memory problem.
I see you're using FireFly, so you must have P5/6.

Your 2nd post seems to show the 1st bucket (single "lump" of rendered image) being repeated for the whole image.

Suggestion: In the render settings, try turning down the bucket size to something a lot smaller. Takes longer but uses less memory. And turn off any stuff that's not necessary...

And start from a fresh re-load of Poser (just to ensure that Poser has as much memory as it can), and with the minimum of background processes working...
I'm probably way off the mark, but that's where I'd start...

Cheers,
Diolma

PS - Is that the "weave" node (with displacement attached) I see there? Nice application of it!
