When configuring a TeamRaiser, in Step 13: Customize Pages under Related Actions we have the ability to Select Banner.

You are presented with a pretty standard Luminate image chooser / file uplaod screen.  However it includes the caviate statement:

Enter the name of the file on your computer or use the Browse button to select the file. Images must be .gif, .jpg, or .png files. Files with a .jpg or .png type will be automatically resized to fit in a 500 x 400 pixel space. The maximum acceptable file size is 2 Mb.

I don't want Luminate to to automatically resize my images.  I want Luminate to leave my images alone.
