In order to know how it works you want to read the Help File and the FAQ in this forum. I am not a geek myself at all. I read the information available. That's all.
So, since you downloaded the KML file you have always previewed the photos:
How to preview your photo in Google Earth
To preview your photo in Google Earth:
- View the photo in Panoramio, and make sure that it has already been mapped. The photo must be mapped before you can preview it in Google Earth.
- Above the photo, click See in Google Earth. You are then asked to download or open a file.
- Download or open the file. Google Earth opens.
In the left Places panel, under Temporary Places, you can see a section for your photos. For example, if your Panoramio username is fotonina, you'll see a section called fotonina's photos. - In the Search panel, search for the place where you mapped a photo. You'll see your photo as a thumbnail, even when other photos are just small icons.
You can preview a photo in Google Earth. When you preview the photo in Google Earth, you see the latest Panoramio photos, including those that have not yet been transferred to Google Earth.
There's no way to preview a photo in Google Maps.
Do you still think someone has to be a geek to follow the above mentioned instructions to preview a photo? Be honest.

2. Photos in Google Earth.
2.1. Why can’t I see my photos in Google Earth?
Please note that Google Earth and Google Maps are not the same. Please read question 2.3 if you don’t find your photos in Google Maps. Uploading photos to Panoramio does not mean that they automatically appear on Google Earth.
First, make sure that the photo is mapped. Then, you must wait for the photo to get reviewed. If the photo is approved for Google Earth, the waiting game starts. Read on for more information about the review process.
All photos uploaded to Panoramio are reviewed by a group of hard working individuals we simply know as reviewers. Mapped photos which are found to be good according to the selection guidelines are selected for Google Earth. The time it takes to select the photos varies since a batch of photos is broken up and distributed to different reviewers. If you for example upload ten photos, these may be reviewed by several reviewers at different times. The photos that are approved will receive a blue compass symbol.
Then, the selected photos are forwarded to Google Earth for final integration into the Panoramio photo layer. This may take some time. Sometimes photos can be put in place days after they were selected, but within two months time is considered normal. This process is not consecutive; the photos which are approved first may show up in Google Earth last, and vice versa. Please note the reviewers are not the same as the forum moderators. As far as we know, the reviewers have never entered the forum, so nobody in the forum knows who they are.
If you want to see your photos in Google Earth almost immediately (mostly within hours), you can make use of KML files available from Panoramio. Click on the link “In Google Earth (kml)” next to your username in the gallery page. Download the KML file and open it in Google Earth. Please note that only you can see the photos this way. Everybody else must wait till your photos are approved and in place in Google Earth before they can see them. Of course, you can send the KML file in a mail to a friend if they can’t wait.
