Table Base and Table Top Combinations

[Blaize5E15]

I wish to automate a process of combining Table component renders to create finished table base x table top combinations. A table base can have upto 15 combinations of table tops (varying in colours and materials). There are also metal rims that are an option for each table top......Then there are several bases that this all will be the case for. The amount of tops will vary from base to base. 

Each render has a white background and there are alpha makes for each render. So as each render is brought into the photoshop file it needs to masked with the alpha mask. this will enable the bases to be seen through the tops and rims layers.

The image needs to be trimmed of the transparent pixels so image becomes the size of the table combination.

Then Saved out as a jpeg.

Simple Structure of combinations would be something as follows

Table Base 1 options

Table Base 1 + Top 1

Table Base 1 + Top 2........

...........

Table Base 1 + Top 15

Then 

Table Base 1 + Top 1 + Rim 1

Table Base 1 + Top 2 + Rim 1

............

Table Base 1 + Top 15 + Rim 1

Then 

Table Base 1 + Top 1 + Rim 2

Table Base 1 + Top 2 + Rim 2

..........

Table Base 1 + Top 15 + Rim 2

And So on.....

Please Help

Can you provide a link to download at least 2 or more complete sets of components per table?

Please make it clear exactly how many variations each completed image should produce.

Perhaps one set with the smallest/simplest number of options/components and another with the largest/complex greater amount?

Real filenames, understanding the pattern of text for each file is critical. I presume that this will be consistent and logical.

Will all files be in a single folder or otherwise? What is the directory structure?

The pixel dimensions of sample files can be reduced from the original sizes as long as all files are processed the same.

Two scripts or processes may be required, one to combine into a single table with options as layer sets and another to save layer combinations into the final flattened files.
