    MoinMoin - ImageBrowserContent Macro
    Version 0.1

    An image browser with a content panel which avoids surge protection.
    
    [[ImageBrowserContent(index, file0, file1, ...)]]
    [[ImageBrowserContent(file0, file1, ...)]]
    [[ImageBrowserContent(index)]]
    [[ImageBrowserContent]]
    
    Where index is the 0 based index of the image to show by default, and
          file0, file1, ... are the images to display

    If omitted, index defaults to 0 (the first image) and file0, file1, ...
    defaults to all image attachments on the current page.

    Comment line 119 and uncomment 120 if you don't want to use the Thumbnail
    action (Javascript comment, not Python).
