to attach photos you need a 3rd party photo hosting website, like Photobucket.
you then copy the address of the photo onto the line that pops up when you click on Photo button.
i suggest posting this question on the Tent Camper/Popup section here, since the roof of a popup is different in some ways to roofs on other types of RV's.
you may also want to go to some Popup-specific forums, like Popup Portal or Popup Explorer.
much more activity there, for popup owners.
i owned two popups and i would go there if i still had them.
