Two things to consider:
 * 1) Perhaps it might work if you used #tag for the gallery tag and used the choose-option tags for just the image that is random. I haven't tried it though, this is just speculation.
 * 2) If the list of image options is very long and needs to be kept updated, you can use DPL instead.
