missed image caption

missed image caption

To the best of my knowledge, Betis vs Real Madrid kicked off at 19:45 UTC. Since all dates and times shown in the IV preview are in UTC, this template would imply that the article has been published before the match even started.
To me it sounds more likely that the date and time in the original article should be parsed according to the Colombian timezone (UTC-5 at the moment), so that 22:39 would be displayed in the preview.

This photo not have a photo caption. The caption is a paragraph.

Second author missing

Easily identifiable "related article" link, should be in <related> tag.

Missing image

Non-essential navigation bar. Useless header. Also, the second picture is intentionally hidden in the original article.

Missing site_name property

Site name mixed with the article title

This is related articles, and it not is formated correct.

This one is not a simple paragraph and can be more clearly identified as a related article.

Missing embedded video (VidWeb; open the article with JavaScript enabled to see it)

<div class="credito"> must be placed inside <cite>

Meaningful formatting not preserved (bold & italic)

Text above picture in the original, ended up below it in the IV.

Time information is missing.

"The subtitle must be shown on the IV page if a subtitle exists in the source."

https://instantview.telegram.org/checklist#6-1-3-subtitle

"A subtitle is a subordinate title of a published work or article giving additional information about its content. If this is present in the original article, a subtitle is required."

"Few publications actually use subtitles. Somewhat more common are short summary sentences that are also shown below the title (and are called standfirst by the British). These summary sentences are usually short and are not part of the article's text. It is advisable but not required to represent them as subtitle elements."

<div class="resumen"

Description in link preview not handled properly.

Admin's decision: https://instantview.telegram.org/contest/dalealbo.cl/template2/issue1/

EXCEPTION! Slideshows must not be used:

...
When the article consists entirely of a slideshow (and its caption/description) and there's no other content.
When the article uses images/videos/GIFs with captions as the main medium (e.g.: travel blogs that show many photos with captions, step-by-step crafting guides, cooking recipes, etc.).
In the cases above, use images with captions (or even plain paragraph text) following one another.

"Galerias" here uses images as main media, text is only short description. Slideshow must not be used.
