some screenshots along the way. http://i.imgur.com/ZL18G.jpg

1. add an alpha channel
2. select the black and cut it (1st image)
3. invert the selection
4. shrink the selection by (say) 10 pix
5. cut the selection (2nd image)
6. select none
7. apply the alpha to neon filter setting as per your tutorial (3rd image)

Another way is to create a "path" from the text and then use a Python 
script of mine to neon-ify the text. It's all explained here (with 
pointer to "engraving fonts" necessary in some cases):



The neon script is described in the "Decorations" page, and I recommend 
reading the "Paths FAQ" page.

An exemple of what you can get with the script;

Btw,  a better format for these computer graphics is PNG, that you phone 
will very likely accept.

[Rob Antonishen]

The tutorial assumes white text on a transparent layer, with a black
layer background.

You can do this by starting with your THEBOLT image and using color to
alpha http://docs.gimp.org/en/plug-in-colortoalpha.html to make the
black transparent.

Then just follow steps 3,4, and 5.

[Gimp-user] Neon effect on jpg ?'s

[Longstreet]

Hello all. Noob here, with a question. I've used GIMP just enough to humiliate 
myself at my lack of knowledge, and am trying to get a handle on the whole 
image manipulation thing.

For a first project, I'm trying to make a wallpaper for my phone. My idea 
involves neon text (from the tutorial on this page 
http://www.gimpusers.com/tutorials/neon-glow-text) on top of a logo I've found 
in a jpg, both of those over a starry night sky.

The text is no problem. The tutorial referenced above was easy to use and 
understand. I thought I could apply the same steps to the black-and-white image 
here http://i211.photobucket.com/albums/bb261/HHMACHSHOP/THEBOLT.jpg
but it didn't work.

I suppose the problem is that I'm starting with two different things, i.e. 
starting from scratch with the text vs trying to manipulate a jpg. I've tried 
experimenting along the way, but it's hard to experiment when I'm not sure what 
I'm doing in the first place. I'm sure what I'm trying is possible, but I'm not 
sure how to go about it.

Any ideas or suggestions? Tia.
