Most people's flame throwers "work" without a jetpack or fuel source... so yours could be separate. With that said... the option to attach it would set it off a bit

As for pictures... thing are often drying/setting/clamped at the end of a build session... so take pics first. Its nice to have pics at various stages, and has several benefits...
1. If you are doing something that won't pass spec later, members will let you know before you spend even more hours perfecting something that won't work. (there have been members who put in the time to build, multi-layer paint, and even black wash/weather something.... only to be told to make a basic change that will require redoing all of it (usually plate shape/size... but could be anything)
2. If we know the direction, we can often lend advice on how to do it better/easier. (don't permanently attach, use this fitting, use this glue, etc etc)
3. Or even advice on how to upgrade/change the design for the better. ("a bla bla greebly would look great there", or "a bit of damage/scuffing/2-tone there would look awesome", etc)
