Telegram's instant view: fails to load .webp and .ico images

Question

I have a problem when trying to create my Telegram's Instant View template, with this error:

Resource fetch failed: https://gdude.de/blog/assets/images/Kaggle-Lyft/task.webp
Resource fetch failed: https://gdude.de/blog/assets/images/telegram.ico

The URLs are valid, I have checked. These are the only two images that fail. Does IV support *.webp and *.ico images?

Answer 1

According to their manual, Instant View is only actually supporting gif, jpg and png.

with the attribute src and the optional attribute href to make the image clickable. Allowed formats: GIF, JPG, PNG (GIF would be converted into Video type by IV)
