Need to buy a Flash slideshow app

Don’t have time to build. Anyone know of a slideshow app that does the following:

  • Loads dynamically (XML, etc.)
  • Thumbnail gallery next to enlarged image
  • Multiple galleries (select by dropdown list)
  • Multiple transition choices
  • Photo captions
  • Dynamically resizes to image format (landscape/portrait)

I have many images in several categories. Open source is great but I’ll also gladly pay for one that has all of these attributes. Thanks for any suggestions.
