Panoramio

Now I tested.
I opened demosite with Panoramio, it is New Zeland
test #1
Open map details and enter West Coast into Panoramio Tag field.
And I saw only images with this tag, if you open link from infowin to details of image, you'll see on right Tags in this photo:

test #2
I get from image this line More photos by ......
I click on ...... and saw its ID
Open map details and enter id (number) into Panoramio UserID field.
And I saw only images with this used id, you can see it in infowin on the bottom right corner by .....

Therefore, it is OK with Panoramio

Thanks for the effort, Dima!!!

Now I got it

I was thinking "Tag" would mean a certain, unique photo ID and not a search term.....

So all working as expected

What if I wanted to show just one single photo from Panoramio on the map?

In my case I am writing a travel guide. And until I do not have own pictures of all places I want to refer to I would like to use the Panoramio ones. So I will write an Article with module calling a part of the map in high zoom factor including the ONE picture.

Is that possible somehow?

Currently you can't do that, because in GoogleMaps API there are only tag and userid restrictions, I call it, and I don't use Panoramio JavaScript Widget API
