The initial string is [image:salmon-v5-09-14-2011.jpg]
I would like to capture the text \"salmon-v5-09-14-2011.jpg\" and used GSkinner\'s RegEx Tool
If you are always looking at strings in that format, I would use this pattern:
(?<=\[image:)[^\]]+
This looks behind for [image:, then matches until the closing ]
[image:
]
