Thanks for the quick reply. I believe that the slide duration be automatically set by the slide's audio clip duration is an important feature. (be it for narration, educational slideshows, or whatever). For example, I have the following to sound byte to sync with slides: http://s135598769.onlinehome.us/clip.mp3 This is just a minute mp3 sample, but in reality, I have some 60 hours of audio that I want to synchronize. In this clip, each time there's a "beep" (which later could would be replaced by a "beepless" version), it's the cue to change slide. The other option is to trim the audio between the beeps and create individual sound bytes to assign with each slide. As of now, it's next to impossible to do it efficiently. So I'm stuck using the old carousel projector, a cassette player and a box of slides in the classroom, instead of a more compact computer projector setup with hundreds of self-executable slideshows in the Hard Drive! One way I see it during editing with PicturesToExe is to be able to visually see the waveform/listen and on top be able to arrange/stretch the slide to match the desired duration. This would involve to paste the entire audio track at once. (which is faster - but that would be a major revision and programming). The other, easier way (programming wise) would be to set the slide duration automatically according its audio clip duration. This would involve cutting the audio in little individual segments. Programming wise it's a minor revision, but more work for the user. - Which is fine as long as it works. It's complicated to sync an audio track to create an educational slideshow. I haven't come across any slideshow software that will be able to efficiently (or visually) sync slides with audio at precise cue points and output an exe slideshow. (I tried many). This is why I think that it should be considered it for a future version. It's a simple feature that seems to be overlooked, yet useful. Thanks, Dimitri P.
