I only made this site after riding from Bangkok to Phuket, so will try and add photos for this part of the trip soon.
The rough route was:
Bangkok -> Kanchanaburi
– > west coast down -> Surat Thatni
ferry over to Koh Samui then ->Ko Pha Ngang
back onto the mainland and further down the east coast to Nakkorn Si Thammarat
Then over to Trang -> Krabi -> Phuket
