The images are only used in one template, activity_statblock. You could take the content of that template, paste it in notepad, and replace all occurances of

$stylevar[imgdir_misc]

with

images/misc/activity/dark

or whereever you like.

If you have a parent style that most of your styles are derived from, you might opt to replace with something like {activity-images} and set a replacement variable for that in the child styles according to which directory is appropriate.

Please note that if you have styles with postbits that vary in certain ways from the defaults, you will have trouble with the JS postbit modifications. You can disable these by setting the postbit modification to default location and remove postcount and remove joindate to no. You can also disable them per-style by removing the content of the activity_postbit_epilogue template in the styles with trouble.
