Thank you to everyone who tried to help me. (I'm not an artist and I guess it shows.) I found a tutorial on layer masks (I've never used a layer mask before) and I finally did it. But sheesh, did it look bad, like a hackjob cut-out copy/paste, not like what I see in the tutorials where you can see all the wispy fine hairs, not at all like what Rod and tranductin were able to do. Guess I'll just keep experimenting. Again, thank you to everyone for your help, you all gave me a much better understanding of what the concept was.

Edit: Well I practiced and finally figured it out. Deciding how much white and black to put in the curves box is really an art form, takes a lot of experimenting!

The duplicate layer will be the top layer. You did it correctly. Its all in how you fill in the white area.
You can as an alternative do it this way.
1) open your image
2) add alpha channel
3) right click add layer mask - white full opacity
4) select the layer mask, using BLACK paint and paint on the mask where you want the IMAGE to show through

Example

Windows 10 tried to upgrade me and crashed my computer; I lost Gimp. I am trying to restore Gimp to what I had. I am trying to put Layersfx back into it.

I have downloaded Layersfx to my Desktop. Then I have gone Edit > Preferences >Folders> Scripts. But I don't know how to get/move the Layersfx from my Desktop into this Script-Fu folder; the Layersfx on my Desktop won't drag and drop, nor will it copy/paste.

Can anyone tell me how I can put this Layersfx script into this folder? Thank you.

Open:
C:\Users\(yourname)\.gimp-2.8\scripts
Right click on your desktop .scm file and choose "copy"
Right click on the previously open folder (C:\Users\(yourname)\.gimp-2.8\scripts) and choose "paste".
Restart Gimp

Thanks, but there isn't any "Scripts" folder in that list (see screenshot). The only way I can find the "Scripts" folder is through Edit>Preferences>Folders>Scripts.

Create yourself an empty folder "scripts" under .gimp-2.8
Then procede

Thank you, worked perfectly. I'd just assumed the folders had to come from the Gimp download, it didn't dawn on me I could just make one (I know, computer-dumb). Thanks again!

Glad you solved your problem.

Thats very strange as GIMP always adds all the needed resource sub folders and rc files for extra addons when it installs itself. After first run it will auto create other needed files in the /USERNAME/.gimp-2.8 folder.
Where did you get your install from?

You should have more folders also.
gradients
patterns
pallets
gimpressionist
scripts
themes
You are missing quite a few.

I just downloaded it from the GIMP site. I got them all the first time I downloaded Gimp (before my crash) but not this time. I just assumed they'd changed something.

Could anybody give me instructions for how I could change this black background to white? I've tried using fuzzy select/delete over a white layer, but I just keep ending up with a transparent background. Thank you.

This isn't as good as a bit more care could give - however, delete all your black with whatever selection tool gives you the results you want, then add a white layer below your cut out and export as jpeg, png or whatever you wish

The problem is, the black is not 100% black. Invert the colors and you will see it is a gradient.

Various ways, none very wonderful.

Try
1. Make a selection of the bulk of the 'black'. Quick-mask or fuzzy is good for this and fill with white leaving just the 'decorations' filled with black.
2. Use color-to-alpha with 'black' as the remove color
3. Remove the alpha channel (make sure background color is set to white)

Gives this:

Thank you. Both methods worked and I have recorded them in my how-to Gimp log, will undoubtedly be used more. Thanks again.

I am trying to get my Bevel Reflect Logo up and running again, but am running into the problem of the Dialog box being too big for my screen, I can't get to the "OK" command. I had this same problem before and people here told me how to fix it. I went back and followed those instructions again, but it hasn't solved the problem. So, can anybody tell me how to get Bevel Reflect Logo up and running in a Windows 64 computer running Gimp 2.8? I have downloaded:

Script-Fu Scrolling Interface Mod Win_x64 in scripts folder
Script-fu-interface-Mod-V1.0-Win_x64.zip
Version: 1.0
Author: GnuTux

Bevel Reflect Logo in scripts folder
bevel-reflect-logo.scm
Version: 1.6
Author: GnuTux

ML Bevel Reflect Source Code in plug-ins folder
MLBevelReflectV2_Source.c.zip
Version: 2.0
Author: Marcel Lancelle & GnuTux

Thank you.

I thought that's what I did. Would you mind taking a look at my plug-in folder (screenshot below) and tell me if I have the right download for Bevel Reflect Logo (on Windows 64 bit, Gimp 2.8)? Thanks.

Nothing should be in the plugins folder except exe,py,and DLL extension files. And maybe a few extra folders that install with certain plugins.
Nothing should be in the scripts folder except scm extensions.

I cleaned out what shouldn't have been in those folders.

I have Gimp 2.8.18 and Windows 10 64 bit.

I have MLBevelReflect ("Application"), and script-fu ("Application"), and Script-fu interface ("C file") [this is Version V1.1] in my Plug-in folder.

I have bevel-reflect-logo ("SCM File") in my scripts folder.

I've gotten the dialogue box to where I can now reach the OK button, but when I click it nothing happens. I've turned Gimp on and off, but that doesn't fix it. There must be something I need to do to turn these things on.

You do not need the c file at all. Remove it.
Also could you please attach a print screen snapshot of the dialog you are having trouble with?
