How do you create hi-res images for image overlay in Google Earth?

I would like to make an image overlay for Google Earth that color codes the counties in Texas. I can’t find a tutorial anywhere on the internet, but have found examples for other states. I would like to be able to separate each county by different colors to easily distinguish them. I was able to find tutorials, however, that explained the process of taking an image and making an overlay, just not how to make the image itself!!! Any help would be much appreciated.

I usually take overlapping images zoomed in and assemble them with Photoshop using the photomerge command.
Start by panning across the state in Google Earth and saving images. Make sure the areas overlap each other from one image to the next. The more you zoom in, the higher res. your final image will be, but also the more images it will take to create it.
In photoshop, open ALL of the images and go to File – Automate – Photomerge and it will match the pixels and assemble the small images to create a large one.
It can be time consuming, but this is the only way I know how to do it for free. Hope it helps.
