P3D v4 Can I use Autogen Annotator when my photo image is in a BGL ?

Hi Folks,

I used AA extensively in FS9 - we had to navigate to the texture in question and load it up for annotating - so can I use AA when my photo texture is in a BGL ?

I have read the LockMart page and it tells you a great deal about what it does but not how to get that fist texture loaded for editing...

Looks a tad more complex than the one for FS9... I'll take any gotcha's anyone would like to share while I get back on my feet with this...
