How to run 'feh' in the background of a script?

[joe at actionline.com]

How can I use a shell script to execute 'feh' so that the image that it
puts on the screen will remain there (until I close it) while the shell
script continues with another operation (like kwrite?

For example, I'd like to be able to use something like this:

feh -x -g 400x400 image.jpg; kwrite textfile.txt <E>

And have the image remain on the screen while kwrite opens the text file
for editing.
