Spot of trouble with clutch

Superglue .... felt pen .... magic , how the f#ck would I know ... over to you Bruce
 
Thats where i do have a hidden talent , bit dodgy on the home mechanics but talented using photoshop and assorted computer multimedia programs, anyone needing image editing let me know, happy to help.
 
The easy way: http://evernote.com/skitch/

Another way - taking a screenshot of the photo in Windows with "Snipping Tool" and then using the drawing function in there to draw the arrows on with the mouse.

A third way: open the photo in the built-in Paint application in windows and paint arrows on it.

But Skitch is easy and makes it look great.
