Need help draping image onto DEM

[MiguelSilva3]

Hello;

I am new to ArcGIS and I need help with ArcScene. I have been trying to drape an aerial image which I exported from Google Earth onto a DEM I created; but I keep receiving an error:

"Base Surface

The layer and specified surface do not overlap in extent.

Verify they are for the same study area."

I have three files:

Contours 

DEM and 

Aerial photo

Both contours and DEM are a perfect match after selecting floating on a custom surface on Base Height in properties for each.

I will appreciate very much any help!!

Thanks

Miguel

Try adding appropriate vertical offsets.

Thanks..,do you have any experience with Aspect and Slope; in ArcScene the results are not quite intuitive:
