Can you trigger a script with `system.opc.readValue` and directly grab the bytestring from the device? I have grabbed images off a Datalogic Matrix Barcode reader over OPCUA as bytestring, but they came from a OPCUA method as a bytestring. Once you do that, I threw them into a db as base64 and used them in reports: > [@Retrieving Base64 Images from SQL Databases](https://forum.inductiveautomation.com/t/retrieving-base64-images-from-sql-databases/80046): > > I have been struggling through making Base64 images work properly in various areas of a job, so seeing as there is no clear information on how to do this, I thought I would make a post to preserve the info I have accumulated. Encoding an image to save in a Database I am using a device that sends me Image data on OPC-UA, so my data will come from a different system than most people will use. When I get an image, I have a python script in my gateway that does the following: import base64 logg… @pturmel has a Blob server driver that will give you better options for using the images. --- _[View the full topic](https://forum.inductiveautomation.com/t/bytestring-opc-ua-tags-in-ignition/102262)._
