Answer 1

Use @webpagebot

You can send the link [up to 10] you want to update to this Bot and it will scan your site and generate the new image thumbnail, site name and description.

Note: You may need to restart your Telegram client to see the updates

Images are cached too. Update them the same way. Be sure they're specified using Open Graph but note you do not need to use the prefix attribute on your html tag to define the OG namespace.

Second solution:

Use a pattern like the following pattern for your web address:

http://{webpage address}?v={number}

For example use this:

Instead of:

http://www.example.com/mypage
