well for the photos you can do this. go to
http://photobucket.com/ and create a free account, then you can upload all you photos there and just copy the img code and paste it in here and voila, pic.
and yes its possible to take out the lower part that holds the pcm, just pull out the pcm, you DONT have to disconnect it, and I beleive there are 2 or 3 push pins or screws, but thats all that hold the bottom part on. but you can either make your own(cheaper) or buy one of these

its just a metal plate with holes to accomodate those original push pins then a bungee cord or something to hold the pcm down. but I would suggest, since that the pcm is safe in the air box, that if you remove it to wrap it in plastic or something to still keep it protected.
