it is very well, you are clever and make me happy.
so the mango persistent working good!
for clearly the step to publish HTTP image as below
step1: (mango in raspberry pi) add mango persistent TCP for get publish xid and setting Host, Port and Authorization key. this step we can add all data point except image
step2 (need only for add image to persistent) if we have data point xid of image already. go to Administration/configuration import/export and export.
setp3 copy code to text edit and insert xid of image directly with the same format.
copy all code and paste back to the configuration and import.
step4 modifying or replacing Mango/web/WEB-INF/snippet/imageValueThumbnail.jsp to be the same as the latest in the repository: https://github.com/infiniteautomation/ma-core-public/blob/main/Core/web/WEB-INF/snippet/imageValueThumbnail.jsp
with 4 step mango in raspberry pi well published to the host.
step5 (on PC) setup mango persistent TCP data source to receive. set some port and authorization same as on sender setting (raspberry pi) and test get status.
all data point form sender side add automatically in to your PC and we got image :)
