There are many unnecessary image loads

Problem

There are many unnecessary image loads, and I don't know what in the configuration needs to be modified to cause this.

Hi @ying2025, thank you for opening this issue! Could you please share more information about the set-up of your JupyterLab instance? Are these images getting loaded when you open a notebook? If you could also share any reproduction steps that would be helpful!

These are from extension manager.

These are from extension manager.

How can I set it so that it won't load these requests?

I only change the

c.LabApp.static_url_prefix = 'xx'
c.LabServerApp.labextensions_url = `xxx`
c.ServerApp.tornado_settings = {
    "headers": {
        "Content-Security-Policy": "frame-ancestors 'self' *"
    },
   "gzip": True,
   "compress_response": True,
    "static_handler_args": {
        "gzip": True
    }
}

Thank you for creating this issue @ying2025.

Clarifying question for @ying2025 and everyone involved in the discussion taking in account that these are from extension manager:

• Does this happen on notebook launch or on extension manager being open?
• If it is the latter, seems like the intended behavior of extension manager. Would adding an option to not load extension images at all or to limit a number of images loaded remedy this?
