so brant:

the feature is already accidentally in there.

Like I said before, we're using Conrad Rider's VisualCube image-generator to generate all of the cube images on the fly.

When you make (or edit) a case group (OLL/PLL/etc) you have an input available for "VisualCube suffix" or something like that.

Before, I just had you input the 'oll' into that box, but you can add additional stuff there.



Reference:
http://cube.crider.co.uk/visualcube.php

All of my cube images are basically generated like this:
http://cube.crider.co.uk/visualcube.php?fmt=gif&size=200&alg=S2M2E2

after the .php part, there are a bunch of different parameters

for example:
fmt=gif makes the image render as a .gif format
size=200 makes the image have dimensions of 200px * 200px
alg=S2M2E2 applies the alg "S2 M2 E2" to a solved cube.

In addition to these parameters, we have MORE available to us that we haven't been using.

For example:
'view' is another parameter we have available to us.
In particular, 'view=plan' makes us view the image from the top of the cube.
Example: http://cube.crider.co.uk/visualcube.php?fmt=gif&size=200&alg=S2M2E2&view=plan


BONUS FUN!!!!

We can (right now!) add 2x2 algs as well.
Similarly to above, just add
&pzl=2 to the end of the suffix




tl;dr
when making the zbll set, make the "visualcube suffix" like this:
zbll&view=plan

if you do this, all generated images will have the zbll 'mask' (which I don't think is anything) and will be seen top-down.
