issue for webnoviny.sk
Full text of following issue:
Slideshow in your template is missing some images from galleries, because you captured pictures only from first gallery while there are two (2nd: https://www.webnoviny.sk/test-honda-cr-z/honda-cr-z-jpg-27/).
After trying same solution as you, I think we should not convert external galleries into slideshow on this site. Here's why:
1. They've actually got at least double galleries for one article. Try clicking on first image in first gallery to open second:
1st gallery: https://www.webnoviny.sk/fotogaleria/citroen-ds3/citron-ds3-jpg-2/
2nd gallery: https://www.webnoviny.sk/prva-jazda-citroen-ds3/citron-ds3-jpg-15/
1st gallery: https://www.webnoviny.sk/fotogaleria/honda-cr-z/honda-cr-z-jpg-2/
2nd gallery: https://www.webnoviny.sk/test-honda-cr-z/honda-cr-z-jpg-27/
I wouldn't be surprised if there are articles with triple and more galleries.
Right now both of our templates don't work porperly with these.
Yes, we can parse them too, but I'm already randomly getting RULES_TOO_SLOW error on both of our templates. And galleries in these examples aren't the longest.
2. Putting long paragraphs (like here https://webnoviny.sk/test-honda-cr-z) from galleries into slideshow's images' captions, as we do now, looks bad. I'm pretty sure there are worse examples. Paragraphs are intended to be read more thoroughly than captions and we're putting them above randomly colored images, which makes them hard to read.
3. Also there are problems with paragraphs duplicating captions (which can be somewhat fixed as you did).
4. Significant part of photos in these galleries is already present in article, so galleries aren't important on this site.
All of this isnt reliable and and produces bad UX.
