@ABHISHEK0S1INGH when are you planning to implement the corresponding frontend code?

[ABHISHEK0S1INGH]

Hi @DenizAltunkapan, I’ve started reviewing the code. Since I’m focused on backend development, it might take a little time to go through everything thoroughly.

@ABHISHEK0S1INGH
Thanks for the contribution!
The implementation of the image upload endpoint is well-structured and technically clean.
However, this PR does not yet fulfill the original issue requirements.

The issue was about sending images in private chats, meaning:

• creating a ChatMessage of type image
• broadcasting it via WebSocket
• extending ChatMessageDto to include image metadata
• returning image messages in /api/private-chats/private
• providing an endpoint to serve the image binaries

This PR currently only handles file upload but stops before integrating the uploaded image into the chat system.

Could you extend the PR to include the missing functionality so that images actually appear as chat messages?

Hi @DenizAltunkapan , Thanks for the detailed feedback!
Understood — I’ll extend the PR to include all the missing functionality and ensure that image messages are fully integrated into the private chat flow (message creation, WebSocket broadcasting, DTO updates, retrieval, and image-serving endpoint).

I’ll update the PR accordingly soon.
