I'm loading a series of images into a pix_buffer using folder_list and [open( messages.  I would then like to send a bang event once all the images are loaded.

1) Is there a way to find out when pix_buffer has finished loading an image?  Maybe pix_buffer_write has something?

2) Is there a way to know when folder_list has finished outputting all the files?

This seemingly easy problem has me scratching my head.  The best workaround I can think of at the moment is to just build in a long enough delay before triggering the finished event but that feels like  a dirty hack.

Thoughts?
