How to make Web module produce different-sized JPEGs for different pictures?

Question

Hi --
Googled this question, searched the "help" on Lightroom, searched Adobe, downloaded the latest version of Lightroom, searched this forum, no help, so I'm asking:
I'm using the Web module in Lightroom (which I've already used to create five other sites) to put together a site. Normally, I just set the JPEG size to "1024" with the "Size" slider under "Image Pages," and normally that's fine.
In this case, however, I'm posting some telephoto shots of dolphins and some of the pictures are cropped below 1024 on both height and width of the raw image, and so LR renders a JPEG that it upsamples and of course it looks terrible.
Is there a way say, "okay, LR Web module, 1024 pixels' width or height is fine for most of the pictures, but these two shouldn't be more than 400 pixels on either dimension?"
In case it matters, I'm running LR on a Vista 64 system, 3 GB RAM.
Even if you can't help, thanks for taking the time to look at the question!

Hi,
The slide duration in presenter is automatically adjusted according to the time of the audio inserted on that slide.
How are you inserting audio on slide ? Recording or inserting  using presenter option ?
You cannot create a movie format like avi, mp4 etc
But you may publish the presenttaion in the swf format which will play in a browser or a swf player. To play in the broswer you just need to have Adobe Flash Player installed on your system. It will play like a movie in the broswer.
Let me know if you need some more help
