slideshow of folder does not work

Thanks for notice.
I’ll check this issue with folder of images. Till then, try this.
You should check if you have images uploaded to the page/post:
-go to the admin panel
-edit page/post
-click Add Media
-in Insert Media, Media Library select Uploaded to this page/post
-If it is stated No items found, you should upload images.

To add images you should:
1.go to the admin panel
2.edit page/post and add [wp-is3dphoto]
3.click Add Media
4.in Insert Media, Select Create Gallery
5. in Create Gallery panel:
6. click Upload Files and then Select Files
7. select image you wish to upload then click Open
8. when image is uploaded set image Title and type word/letters in WP-IS Photo Gallery Link (for example img)
9. For every image you wish to upload repeat steps 6-8
10. Click Create a new gallery
11. in Gallery Settings choose Link to Attachment Page
12. click Insert Gallery
13. on edit page/post it will be added [gallery ids="......"] delete this and leave just [wp-is3dphoto]
14.click Update
This should work (WordPress version is 3.5.). Here is link with gallery on post https://lakesinserbia.com/gallery

That workaround is not what I wanted. I have a folder of images I want to show, not upload them to the page.
And there would still be the problem with the script not running, and with the missing position:relative CSS.

Ok. You should check in WP-IS Photo Gallery Settings if you entered correct path to your folder. This should be the path to galleries from Web Root.
For example: Your folder named gallery is in wp-content folder. Then you should:
1. enter wp-content/ in WP-IS Photo Gallery Settings in space for Folder Path;
2. Save shanges;
3. Check if your folder is in list for – These folder galleries were found. If it is then go to step 4. If it is not then you did not entered the correct path.
This should appear in list [wp-is3dphoto dir=gallery]
4.edit your page and enter [wp-is3dphoto dir=gallery]
5.Update your page.
And this works.

Please reread my original post. I have the generated HTML in the page, but the script does not run and the CSS is wrong.
