read is a method of css.io.XPersisObject, and intended to read the object itself - i.e. the image control model - from the given stream. That's not what you want to use, believe me :) Unfortunately, there are only two ways how to put an image into the control: - the ImageURL property, pointing to an image file - the connection to a binary database column Since you say your image results from a database column, I wonder why you need explicit macros. Normally, it should be sufficient to put the control into a dedicated logical form, bind this form to your database/table, and the control to the binary column in question. If you definately need macros, then your only option is to write the image into a (temporary) file, and set the ImageURL property appropriately. Since both options are not really satisfying, you might want to submit an issue requesting that an image control can be fed with an image explicitly. Should not be too difficult to implement.
