Hello everyone,
Im trying to finish my Power Apps and im stuck at a picture function. In my App you can answer different questions and upload photos. You upload the text on a sharepoint list and the pictures on a document library. They are connected through the filename you can enter when you start the App.
I created a flow with a html template containing the dynamic values:

I filter the lists in a Get Items block with filename eq 'Ask in Powerapps'
Now i want to do the same with pictures. i tried to apply this guide here: https://powerusers.microsoft.com/t5/Building-Power-Apps/How-to-load-an-image-for-onedrive-into-html-on-Power-Automate/td-p/1385389 from @WarrenBelz But i fail at the append to string block where i cant enter anything as Name.
Maybe my conditions are totally wrong and its much easier to use an Attachement? Hopefully you have a solution for my problem
