This installer for SharePointDesigner has the old Microsoft Picture Manager bundled with it - a very handy image editor.  It is useful for tweaking brightness, contract and colour settings as well as for cropping and re-sizing.

Use the 'Customize' install option.  Choose 'Not Available' for everything and then look in the Office Tools and change the Microsoft Office Picture Manager to 'Run from my computer'.

After running - Untick the option to install updates.
