How to Update Cover and Link Text

Updated 09.11.2026 2 min read

When you send a link to a gallery or scene in social media and messengers, it displays:

  • preview image — the gallery cover with its position applied, showing the gallery name, the shoot date (if set) and your name; if the cover is a video, a frame from the video is shown
  • title and description — the gallery name and “Photographer” with your name

A link to a scene shows the same preview as a link to the gallery. To change the cover and its position, see Gallery Cover.

After the first send, this data is cached (temporarily stored on the social network’s or messenger’s side). Therefore, even after updating the cover or link text, it may still appear with the old information for some time.

To apply the update faster, the cache can be cleared manually.

How to Clear Cache in Telegram

Use the bot: @WebpageBot

  1. Open the bot in Telegram
  2. Send it the link you want to update
  3. Wait for the bot to update the preview

How to Clear Cache in Facebook, WhatsApp, and Instagram

Use the official tool from Facebook:

https://developers.facebook.com/tools/debug

  1. Paste the link into the field
  2. Click on the Scrape Again button
  3. After this, the cache will be updated

Universal Cache Clearing Method

If you do not have access to the tools or they did not work, you can change the URL of the link.

For example:

Was: https://yourname.gallera.io/workshop

Will become: https://yourname.gallera.io/workshop?v=1

You can add any parameter after the ?, the main thing is that the page continues to open.

This will make social networks perceive the link as new and regenerate the preview.

When It's Needed

Clearing the cache is useful if you:

  • updated the gallery cover or changed its position
  • changed the gallery name, the shoot date or your name
  • want the link to look current upon resending
