VS 2008 - Split New String (Preview Image)

I have this as code to run the program
Process.Start(ListBox1.SelectedItem.ToString.Split(New String() {" "},
StringSplitOptions.None)(1))

Which used to work but then I added a "Preview image" function like this :
(ListBox1.SelectedItem.ToString.Split(New String() {" Image:"}, StringSplitOptions.None)(1))
I now discovered that the first code is useless, because it selects everything after " " to run, including the "Image:"

This is how a listbox item is stored:
Tomb Raider Level Editor - Original C:Program FilesTomb Raider - Level Editor omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp

As you can see it'll use this
C:Program FilesTomb Raider - Level Editor
omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp
to run
Is there any way I can make it choose the path from " " and when it finds "image:" it stops?
