Making & Alligning Overlays
Firstly, Go to the "Add" menu in GE, and select "Image Overlay", put your image URL in the "Image Locaion" line, and give it a name -- now to allign the overlay.
Images 1 & 3:
The poles, when you zoom in really close you can pull the image right down so theres almost nothing uncovered, its like tightening the drawstring on a bag - this will make the image sit better vertically, unless the image is unproportional (which in this case - it isnt)
this is the point that lets you spin the image around ontop of the globe freely without adgusting the edges, it is in the "middle" of the image. use this for the fine tuning i was talking about
the "+" where the two "outer" edges of the image meet [or dont meet, depending on if you are doing a whole globe overlay, or just a city]the markers look like -| |- when seperated.
I cant seem to get these together seemlessly, but its only a slight gap.. this is where you decide how "wide" the image is (how much of the globe gets covered)
Fine tune this part, becareful because once they start overlapping it pushes the other edge out of the way and ends up misaligning you
the <> thing to the right of the image is where you can rotate the image, you usually wont need to do this in the case of whole globe overlays though.
Other: If you are doing just a small overlay over a certain city, you can use all the edges to drag an image into shape - often the photo is out of proportion to begin with so it will take some streching, maybe even some rotating before it looks right!
Phew, thats that.. any questions?
yes that right; zoom out to fine-tune, zoom in to check it, use about 80% opacity. -- the image wont move at all from where you placed it while you are zooming.
PETJE: And by zooming in I can see if the overlay is correct at detailed points, but i have to zoom out again to adjust when necessary, is this true?
I hope this helps you all, if you have any further tips or if I've forgotten something, feel free to add on, or ask me any questions - I'll try answer them as best as I can

Overlay Resolution Problems
I'm trying to put some hi resolution map overlays into Google Earth Software.
I'm trying to push this thing to the limit, using a very large file size. For some reason, the larger file size I use for my image overlays, the more distorted the quality becomes.
It seems that the software will take a large high quality image, and then reduce the quality until it fits a predetermined size, and then displays it on the map.
If I break up a large image into 2 smaller images, the quality is noticeably better. If I break a large image into 4 or 8 smaller images, the quality is better yet, starting to approach the original file. The problem is that I have to align all of these pieces on the map, and it's extremely time consuming.
The overlay size is covering about 50 miles × 50 miles, and I'd like to get bigger eventually. Can anyone tell me if there is a file size limit, or a better way to keep my quality high when I import hi res overlays?
Feel free to talk technical, I have a pretty good grasp on digital imagery. I also have a very great machine with 4 GB ram. I'm really hoping I can get this to work, it would be soooo sweet. Does the subscription package have better overlay support?
Can anyone help me put a building on an exact location...
My first time on here. I was wondering if anyone could help me by explaining how I can put a building on an exact location. I managed to get it in the right hemisphere however, it is in the water about 200 miles from land and I don't actually know the depth. Any suggestions are greatly appreciated - oh by the way I am using a Mac and I created the file in Sketchup.
Many thansk in advance.
