"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It doesn't mean that exactly. What it does mean is to match anything regardless of case--but that doesn't limit it to matching words. In your particular situation, you will match any version of those particular extensions. But overall you are correct in what you think it does  = )

The regex pattern, broken down:
(?i)  ignore case
\. match a literal . character
(gif|jpe?g|png) match any one of gif or jpg or jpeg or png
$ match the end of the string

Open in new window

So to summarise it means to match a file with name ending in .gif, .jpg, .jpeg or .png.
