Image selector

Image selector can extract src attribute (URL) of an image. If responsive image size configuration is present, the selector will attempt to extract the url for the largest image available

Note! When selecting CSS selector for image selector all the images within the site are moved to the top. If this feature somehow breaks sites layout please report it as a bug.

Configuration options

  • selector - CSS selector for the image element.
  • multiple type - The way multiple extracted images should be handled.
  • column count - the number of columns returned when multiple type is set to Multiple Records in Multiple Columns

Use cases

See Text selector use cases.
