Please better explain your scenario and use case. I bet you can solve this within the execute_command script when include-command-output-in-response is true.

OK, let's kepp it simple— every 5 minutes a new complicated image it is generated on the server, output.jpg
I need the webhook to display the latest image generated on the server, using webhook.
This is the setting:
{
"id": "itst",
"include-command-output-in-response": true,
"response-headers": [
{
"name": "Content-Type",
"value": "text/html"
}
],
"execute-command": "echo",
"pass-arguments-to-command": [
{
"source": "string",
"name": "<**meta1** http-equiv='Content-type' content='text/html; charset=utf-8'/><html style='height: 100%;'><head><title>test</title></head><body style='margin: 0px; height: 100%'><img style='-webkit-user-select:none; display:block; margin:auto; padding:env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);' **src=output.jpg**''></body></html>"
}
]
}from webhook.

Assuming a Linux host, try something like this:
{
"id": "itst",
"include-command-output-in-response": true,
"response-headers": [
{
"name": "Content-Type",
"value": "text/html"
}
],
"execute-command": "/path/to/showpage.sh",
"pass-arguments-to-command": [
{
"source": "string",
"name": "/path/to/output.jpg"
}
]
}showpage.sh:
#!/usr/bin/bash
echo -n '<**meta1** http-equiv="Content-type" content="text/html; charset=utf-8"/><html style="height: 100%;"><head><title>test</title></head><body style="margin: 0px; height: 100%"><img style="-webkit-user-select:none; display:block; margin:auto; padding:env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);" **src="data:/image/jpeg,'
base64 -w 0 $1
echo '**"></body></html>'from webhook.

Thank you, I fix it like this, it works now:
#!/usr/bin/bash
echo -n '<meta http-equiv="Content-type" content="text/html; charset=utf-8"/><html style="height: 100%;"><head><title>test</title></head><body style="margin: 0px; height: 100%"><img style="-webkit-user-select:none; display:block; margin:auto; padding:env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);" src="data:image/jpeg;base64,'
base64 -w 0 $1
echo '"></body></html>'Not particularly elegant; it clutters the logs by logging every single image in its entirety.

Where is this being logged? Unless you're running webhook with debug enabled, it should not log the response body. Please explain.

I run it like this:
webhook -hooks wb.json -hotreload -logfile webhook.out -port 80&
I think anyone should run it like this. It is one of your strong points—at least for me was the deciding factor.
Maybe we should work on: command output, not to display the entire response body.

@actuariat,
I'm glad this issue is resolved for you.
I've opened a separate issue about adding the ability to control command output logging.
