I just started using the Google map plugin, and it works mstly OK, except for when I click on a thumbnail on the map (after clicking on an image's 'pin' on the map).

As an example:
http://www.cbphotos.ca/gallery/index.php?album=travel%2Fadk_geotag

If I bring up the map and click on an image thumbnail, I get a 404 error, and it looks like the URL has some character substitutions... If I cut & paste the URL from the 404 error page it works, but the URL in the location bar has extra encoding. For example, the location bar might have:

http://www.cbphotos.ca/gallery/index.php%3Falbum%3Dtravel%252Fadk_geotag%26image%3DIMG_2840.JPG

...but the URL in the 404 is:

http://www.cbphotos.ca/gallery/index.php?album=travel%2Fadk_geotag&image=IMG_2840.JPG

I've done enough PHP coding to know that it might be something with the PHP quote/encoding settings on my web server, but I was wondering if this issue has been seen before and what I could possibly do to resolve it. Any help would be appreciated.

Thanks,

Looks like an encoding of the ampresand. Please trouble create a ticket for this.

(I presume you are running zenphoto version 1.2.3. If not, please update and see if the problem still exists.)

I found a workaround (for me) - enabling mod_rewrite fixes things (I had it deactivated, as you can probably tell from the URLs above).

I've noted this workaround in the ticket that I created to track the issue.

i dont find it useful this plugin
what it does exactly

It will show a worldmap of the location an image was taken. But for this to work, the image must be geoencoded.
