JSON Path Autocomplete in VS Code using JSONSchema

In VS Code, there are several tags which trigger autocompletion and validation for local file path references. For example, when entering an img tag:

I have a json file which stores the metadata for an image grid, and I'd like to try to add a validation that the image path is typed in correctly. For example, here's an a json file that contains items with image paths and other metadata:

_images.json

[
    {
        "color": "red",
        "path": "./images/kitten.jpeg" /* identify value type as local path */
    },
    /* ... more items ...*/
]

And here's a JSON Schema Definition which has been applied to the vs workplace settings:

_{.vscode/settings.json}

{
    "json.schemas": [
        {
            "fileMatch": [
                "/images.json"
            ],
            "schema": {
                "$schema": "http://json-schema.org/draft-07/schema#",
                "type": "array",
                "items": [
                  {
                    "type": "object",
                    "properties": {
                      "color": {"type": "string", "enum": ["blue", "red", "green"]},
                      "path":  {"type": "string", /* what to put here */},
                    }
                  },
                ]
              }
        }
    ]
}

Is there any way to check local file paths using JSON Schema Validation or some alternative way to tell VS Code that a particular field is representing local file references?
