Link to onsite dir & index.htm page

[jwzumwalt]

I need to link to an onsite dir & index.htm page
(I have numerous media directories and I have my own custom php page that creates thumbnails for a gallery - it automatically creates a index.htm in the subdirectory)

When I create a link to the index.htm file I get a "Forbidden" error. How can I allow index.htm to run in that sub directory?dir &
