Spanish nudist beaches are wrong

Most names of Spanish naturist/nudist beaches are heavily misspelled and contain almost no info at all. I tryed to correct a few but I checked back today and none of my corrections have been registered. Also, I do not see anywhere where I can put up pictures of such beaches.
We happen to live in the region with more naturist beaches in Spain and only one is listed but really badly. Some are doubled but with mistakes in both entries.
Can someone tell me how to proceede to fix all that and put up pictures?
Thanks
