Description
Description:
When uploading an image through the web client (not sure about mobile, but believe it's no different), the thumbnail is not resized to a smaller version, but rather it's the full-size (shrunk to fit, but still the full-size image). This makes loading chats with images slow due to loading the full size for all thumbnails.
Steps to reproduce:
- Upload an image into a chat
- Use F12 dev tools to note the size/dimensions of the actual thumbnail file
Expected behavior:
A smaller/resized thumbnail should show inline with the chat (clicking should obviously open a larger size)
Actual behavior:
Server Setup Information:
- Version of Rocket.Chat Server: 3.14
- Operating System: Ubuntu
- Deployment Method: native

Research direction
The issue names no files, tests, or entry points. Start by reproducing the upload flow in the web client and inspect the thumbnail request in browser developer tools; done means inline images load a smaller resized file while clicking still opens a larger image.
