It appears that the main man for photoplog has not posted on his forum since December, so probably not much more going on with it.
I have photoplog pro running on vb 4.x.x and now appear to have a problem with the index page formatting since upgrade to vb 4.1.2
see here, but to ask the question on the photplog pro troubleshooting forum I would need to pay another $35 for a year's support and I'm not prepared to do that if he is no longer active.
