This is a DB-aware image control. The image control connects typically to a DB string field and allows to show the content of the DB string field as an image referring to the URL in the DB string field value.

The TWebDBImageControl is connected via DataSource and DataField properties to a dataset.

For setting generating the proper image URL from the DB field value, two additional capabilities are offered.

Property Description
BaseURL Sets the optional URL prefix. In case the DB field only contains the image filename, BaseURL can be set to the full HTTP(S) URL specifier
OnSetURL This event is triggered with a var parameter AURL that can be used to transform the DB field value to the required full HTTP(S) URL.
