What you need to do is to make part of the image transparent. The steps
that you outlined in your original post won't give you what you want.
If the subject in your PNG image has a _distinctly_ different color than
the (outside boundary of) the subject, you can just use Fuzzy Select
Tool to create a selection covering the background and just cut (i.e.
delete) it. The deleted pixels will become transparent.
If, on the other hand, your subject gradually fades/blends into the
background, you need to do something a little more complicated. The
following is a modified version of a procedure I recently posted in
another thread:
1. Open the original image in GIMP
2. Use the Fuzzy Select Tool to create a selection of the background.
Experiment with different threshold settings to obtain a selection that
doesn't leave too much of an outline of the background color around the
subject you want to keep. (A threshold setting of 60 worked reasonably
well in my experimentation.)
3. Give the selection feathered edges. (From the Select menu, select
Feather... and set the desired thickness of the feathered edges.)
4. Use the Color to Alpha function under the Colors menu to convert the
background to transparent. The "From" color should be the background
color to be removed.
5. Save the resulting image as a PNG file.
Let us know how you make out.
