Bulk drag-drop of full perm textures, and perms: Must textures be copy only or full perm?

Question

QUESTION 1: I have a folder in my inventory with all full-perm textures from my "fav" outfit purchase boxes.  The images have already been extracted from purchase boxes over time, and renamed using keywords (which I had used before in a different, huge-LI vendor)...  There are a lot of them.  

Must I upload them in eaches (time), or is there a way to drag-drop many in a single motion (either from sl inventory, or from my hdd) given that they are all full perm, and all renamed to auto-catch tags?

Trying Bulk Upload, all full perm textures (six-ish), drag and drop from HDD to Browsers Chrome, then Edge, then Firefox, then installed Opera, and no bulk drag/drop works under top nav Import Snapshots (all 4 browsers), and under my Import top nav button no dropdown appears at all to choose from (all 4 browsers) so I presumed that button is for Premium only (which I am not at this point)?  

So is it that BULK drag drop of all full perm items does not work anywhere?  

Or is it that I have not found the right tool yet?
 

===========================================

*Answer Question 2 (self):  Textures must be Full Perm

QUESTION 2 ANSWERED: I see some places suggestion that all textures must be full perm, but other places in reference mentions that they must be "yes-copy" perms (suggesting that a no-mod/tran image that is yes-copy *can* be uploaded/work).  What exactly are the minimal perms required, to upload an image (made by an avi name other than me = a seller/me as buyer)? So far I am loving this!  With bulk, well, it would/will be heaven with coffee! Please and thanks!

Answer 1

You cannot drag textures from within your inventory out of the viewer window.

However, both "Import > Import Snapshots" and "Import > Add Items" import tools support dragging and dropping multiple image files from Explorer / Finder into the respective areas:

Regarding the permissions question:

In order to add a texture, its UUID must be obtainable (since the only way to export a texture out of SL is by UUID), either by you in the viewer or a scripted device. Obtaining the UUID is only possible if the texture is full-perm.

Great news-thank you!  

Follow-up Question:  I am using Chrome, and I see "Import" in top nav area with an arrow pointing down (same as in your screen captures above),

BUT when I click "Import" or "arrow down" nothing happens - ie I have no options available to me under "Import" that I can choose?  

Not sure why it isn't showing me any options?  No bulk uploads for me until I figure it out though.  Thanks for the help!
