Clipping a aerial JPEG or SID file

[balajishivaji]

Hello

I am new to ArcGIS and am trying to clip an aerial using either a JPEG (rectangular area - 500MB) or a SID file (whole city-3GB). Basically I want to draw a polygon shape the way I want to clip the aerial and clip it and save it so that the file is not too large. I have played around with ArcMap a little bit but not too familiar with the tools. A detailed step by step process will be appreciated.

Thank you

To draw a polygon, do I need to create a new layer? If so how do I need to create a layer?

I figured out how to create a layer.

After I draw a polygon, how do I put that in the layer I just created?
