Feature Request: Support for image upload in Deck comments

[knghia2902]

Hello Team,

Currently, in the Deck app each task (card) provides a Comments section that allows users to discuss specific issues. This is very useful for collaboration. However, comments only support plain text/Markdown, and images cannot be uploaded or embedded directly.

For many real-world cases, when team members are discussing a task, they need to share screenshots, diagrams, or photos directly inside the discussion thread. Having to upload an image separately to Attachments and then copy the link into a comment is inconvenient and interrupts the flow of collaboration.

My suggestion:

Add the ability to upload images directly in the Comments section of Deck cards.

Allow inline display of these images within the discussion thread (similar to how chat apps or GitHub issues show images).

Optionally, integrate with the Attachments system so uploaded images are stored consistently and remain linked to the card.

Benefits:

Improves collaboration by letting users share visual context quickly.

Makes discussions inside a task more complete and self-contained.

Reduces the need to switch back and forth between Comments and Attachments.

Thank you for considering this improvement to make Deck an even more powerful tool for teamwork!
