Photography

right click on the photo as it arrives in the submission thread, and copy the image location.
Then keep a list of them as they come in for later.

Before I start making the voting threads I select all of them, copy, and paste them into an empty (dummy) window in DU and see if they all come in properly by clicking on "preview".

Then, as you make the voting threads for the poll just paste the location link underneath the title.
As I make these threads I check them very carefully for spelling of the title, if the title is with the correct photograph etc. by exactly that method. I'm sure there are better ways, but this works for me. As long as you have no title in the empty DU window there is no danger of accidental posting.

I hope this makes sense,
and thank you for your response. I will pin it in a day or so. I think one has to be on a specific mission to go look at pinned threads and it could therefore get lost without folks knowing about it.
