I want to create a gallery post, set “gallery” and doesn’t work. On the home page shows a collage of three photos, but when I go to post there is no gallery, only a traditional photo layout. The same with slider, pictures doesn’t open with the gallery option.
I’m not sure what you mean by “only a traditional photo layout”. Could you please post a link?
You are not using the gallery shortcode. You should open the media uploader, click the gallery tab and select “Insert Gallery”. If you also want the lightbox effect you should select “Link thumbnails to image files”.
so, now I have gallery, but it doesn’t open like this: http://demo.onedesigns.com/pinboard/?p=174, but each image individually:

in edit gallery have only reverse orden, random order, link to media file and page annex.
You don’t have link to media file, you have link to attachment page.
For some reason the “link to media file” option is not always saved the first time. Maybe a WP bug. I need to redo the save gallery a couple of times then it works. Or it could be caching (but I use CTRL F5).
