There is no author of the article.

Incorrectly designed subheadings.

This image is not part of the article. It's a thumbnail for related article. Related article links are optional, But Images are rudimentary.

- The slideshow uses small thumbnails instead of original photos (can be done better, see my template).

- Gallery title isn't in the slideshow caption. Also it's better to include the actual title.

- Slides' captions are missing. You can see them if you open the gallery on the page.

This is a gallery page, it has more than one photo.

Broken formatting.
The photo title and credit should be separated. That's not "Simona Guatieri Zdroj".

#issue2 follow-up

Still, the images are present on the page and missing in IV.
You have a point about specific slide links. And my implementation supports such scenario: it shows current photo first, and then the rest, just like the target page.

And yeah, you have to separate the title and credit by something more than a space. It's not just different words, it's different sentences.

It’s an article. IV must generate.

Thumbnails are used for the slideshow. Full-sized images should be used instead.
