I have several images loaded in the Media section of the power app. They are .png files.

I have a Gallery and within that an Image control. I am attempting to load the images dynamically using a Collection as the datasource. The datasource is working correctly, I see all the values populated.

How do I make this reference the image in the Media gallery? This always returns of data type text. Is there a way for force cast it to type image?

ThisItem.ToolImage

Also when I hard code an image reference just by the name, such as OneDrive, I see the image repeat in the gallery control just fine.

Thank you for the ideas! I will use the Switch Case method. (It's unfortunate there isn't a more elegant way of handling setting of data types.)

Hi @RJCTF,

There are two ways to get the functionality, but neither may be suitable for your model. The first is to use the existing collection and put this in the Image control in the gallery
Switch( ThisItem.ToolImage, "OneDrive", OneDrive, "Image2", Image2, . . . . . . )

the issue is that the String "OneDrive" has no relationship to the Media Image OneDrive

The other way is manually collect all the elements of the Collection
ClearCollect( colWhatever, { Field1Name: "Field1Data", Field2Name: "Field2Data", Img: OneDrive }, { Field1Name: "Field1Data", Field2Name: "Field2Data", Img: Image2 }, { Field1Name: "Field1Data", Field2Name: "Field2Data", Img: Image3 }, { . . . . . . } )
