Adding TIFF aerial to dashboard - black background.

[CourtneyWatson]

I've added an aerial to my Dashboard that I have published as an image service  but there is black in the background where there is a 0 value.  Normally I would remove the symbology in the properties but I don't have that option in AGOL.

Is there a way I can publish the aerial without the black showing?

@CourtneyWatson if you're publishing from Pro, you can either set the 0,0,0 values to transparent in the symbology settings:

...or you can create a Clip Raster Function and clip your raster by a polygon feature.

or you can Mask the black areas by a polygon feature
