I am yet to have a good look through your post but there is a total post limit of 10Meg, I have also made the total JPG image file size as 10Meg so it seems it's possible to post a photo that will consume the total Post size..
This limit appears to be a fixed limit within the forum software so for us it means we need to:-
A - Reduce all photo's to bring down the total upload size..
B - Separate the story up to several posts
C - Post the photo's on a remote share site such as Photobucket and install links..
One nice thing the forum has is the ability to reload photo's to an existing post so if you resize all of your photo's then update the existing photo's this should allow you to post additional photo's..
I hope
