A lo mejor me excedo un poco, con la cantidad de código, o incluso podría haber adjuntado un ZIP, pero te pongo el código que yo utilizo para enviar un correo a través de Indy, directamente desde el programa Delphi, y además dentro de un Thread.
Los correos que yo envío, pueden contener una imagen en la cabecera del correo, y otra en el pie del mensaje. Supongo que lo mismo se puede aplicar a cualquier imagen en cualquier parte del texto.
Tienes que fijarte especialmente en los diferentes 'tipos' que se pueden definir.
Además de las imágenes de principio y final, se puede añadir cualquier otro fichero adjunto, diferente de las imágenes.
Espero te sirva :
