Here is the download link to the circa 2007 satellite imagery of Strabane in KMZ (Google Earth) format.
To use: Open the file inside Google Earth..
If you wish to use other KMZ maps of Strabane (see Downloads section) with the new satellite imagery in Google Earth, then load the satellite imagery first and the map imagery second. To see through the maps adjust GoogleEarth's opacity slider.
Example: 1905 Ordnance Survey overlaid on the new satellite imagery in GoogleEarth
For multiple overlays I would recommend using a computer with at least 3 gigabytes of RAM.
