"Change Image Clips Path
Change your Image Clips to a different file with the same name but different extension.
You could do it with [ external files : search and replace ] option but this way is faster when you only need to change formats.
You can set a name prefix to change only those clips that matches it.

Convert PSDs
Use Photoshop and convert PSDs to different formats such as TIFF, TGA, JPG, etc.
Resize, Alpha and Compression options available to those formats that supports them.
- Compression: TIFF uses LZW, TGA uses RLE, and JPG, Quality 6 (10 with Compression Off).
- Softimage PIC option works with Adobe Optional Plugin or Matthieu Fauqueux PIC plugin. I don't think it would work with another plugin.
- DDS is only experimental. I don't remember exactly what options did I use, it was for a projects from a few months ago. DDS has tons of options. If you can script a little, you could use Photoshop's ScriptListener and edit my VBS file.
The Name prefix feature works also with Convert PSDs, so you can convert only those files that matches your prefix setting.
You can save a preset file in the Addon folder to load your custom settings automatically.
Tested only with Photoshop CS5 64bit. But I think it should work in older versions too."
