Trouble with batching filters sequentially

Question

I have an animated sequence of about 300 images which I'm applying to a single base image via the "Glass" filter (creating another animated sequence with the filter).  To do this manually, every time the Glass filter is applied I have to load a new source image in the sequence but I can't find a way to do this through automation (I would need the automation to pick the next file in the folder as a reference for each application of the filter).
Is this possible to do in Photoshop?  I'm using CS4 Extended.  Any help would be greatly appreciated.

If you can do that, I would be incredibly greatful as it would not only save me hours of painfully boring work but it would also open me up to making changes down the road (as there is always something that needs to be tweaked).
The current process is this:
(Starting point- I have the original document open "basebackground.psd")
1)  Filter > Distort > Glass
2)  Within the Glass filter, there are 2 pulldowns next to "Texture:".  The first allows me to select a number of default images or the last used custom image (which has to be a .psd).  The second is the single option to "Load Texture..." which is what I use to get the next custom image in my already rendered blackwhite001-300.psd sequence.
3)  After applying whatever number I happen to be on, I cut the canvas size down to 256x256 (as this was a 3x3 grid of 768x768- this allows me to get rid of tile seams that would have been caused by the edges in a 1x1 grid).
4)  With my 256x256 tile ready, I then do a Save As... sequentially from 001-300
5)  After the tile is saved, I undo the document history back to my starting point so I can repeat the steps but this time, using blackwhite002.psd instead of blackwhite001.psd when I get to step 2.
The details from my best attempt at a Glass filter action are as follows:
Effect:  Glass
Distortion:  15
Smoothness:  4
Tescture Type:  (file path to my my blackwhite001-300.psd)
Scaling:  100
Without Invert Texture
In addition, the original document is RGB with 8bits/channel.  If there is any other bit of information you need, please let me know.
