src
Sets or gets the file location of the image.
Description
Setting the src property changes the displayed image to the image found at the new src value.
Getting the src property returns the location of the current image file.
The image file can either be an image file from the Media Manager or an external file from any web location.
The URL formats supported are:

  • Images from the Media Manager: wix:image://v1//#originWidth=&originHeight=[&watermark=<watermark_manifest_string>]

  • Images from the web: http(s)://

Thank you,
Issue was fixed, just wrong naming convention of column data exp: column name “name7cateogry” that naming is not warning but cant get data.
