dynamics crm - Trigger a plugin step on "entityimage" change -

i created plugin should upload contact entity "entityimage" external storage.

the code should works (it works console app), unable add step trigger on "entityimage" change can't find in filtering attribute list in plugin registration tool.

is there way trigger plugin when "entityimage" change?

regards,

reviewing contact's entityimage field in metadata browser indicates "virtual" field, may why unavailable filtering attribute.

also, according sdk there not appear other message available besides "update" on contact used indicate entityimage has changed.

and, changing image through ui create audit history entry, however, generic "update" entry, old value , new value blank.

it appears triggering plugin on change of entityimage field not possible, nor there appear oob hooks see if field has changed.

the other think can think research change tracking. otherwise looks may have upload image on update of contact.

or, sync image url's crm external system , compare 1 in crm external system before uploading.
