getExtSrc: Non-Image Element Retrieval

When the mouse hovers over a non-image element, getExtSrc can be used to return the image URL directly.

Example: Find Image Near Button

getExtSrc: function () {
  if (this.tagName === 'A' && this.className === 'msk') {
    return this.previousElementSibling.src.replace(/\?param=\d+y\d+/, '')
  }
}

Return Value

• string: Single image URL.
• array: Multiple image URLs.

Notes

getExtSrc is only triggered when the target is not an img element, suitable for scenarios like cards, buttons, or video covers.
