Hello hoa

Thank you for your purchase.

Sorry for the late response. Wednesday 1st and Thursday 2nd were non-working days in our country.

I see that that column is "string" type. To add a picture in a string column, the content needs to look like this:

<img src="http://url_to_the/photo.jpg" height="42" width="42">

Defining height and width is optional, of course.

I hope this helps.

Best regards.
