    Accepted Solution

    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.
