Selecting multiple photos

[Gilbert Despeghel]

Hello to all of you,

I have 3 different exposed pictures , opened in GIMP.
Now I want to select all 3 of them to blend them in the HDR Efex Pro 2 NIK-collection.
As for now I can only open 1 picture in HDR Efex Pro 2...
But I say a presentation on YouTube where someone used HDR Efex Pro 2 to blend multiple exposed pictures...but not in GIMP.

So my question is : Can I select my 3 different expose pictures in GIMP to open them together in HDR Efex Pro 2...?

Thanks in advance,
