I don’t think so, you just need to upload your images and files
separately. You should have a folder of items that PhotoFlow created,
place the items alongside your HTML files on your FTP server using an
FTP app such as Transmit: http://www.panic.com.
If this doesn’t work, move them into your Resources folder (this is
where the SWF file lives, the files either need to be with the page or
the SWF, I can’t tell which without seeing them though).
