We have a cached tile service for aerial imagery. It supports  multiple image formats:

Below is the service description (deleted some info for clarity)

The default image format is a JPG.

I.E.

http://MyDomainName/MyInstanceName/rest/services/MyServiceFolderName/MyServiceName/MapServer/tile/13...

returns a jpg image.

Is there a way to request the same image as a png instead?

I can make an export map request as a png, but I really want to use tiles. Do I have to access the cached files from the virtual directory somehow?

Or is it just not possible?

Notes:

I'm a web developer, not a GIS Admin.

Currently 10.1 but moving to 10.3 shortly.
