Lightroom Flash Gallery Image Size too Small

[Montypop]

When using LR to create a flash web gallery the image size is too small even when I select "LARGE" or EXTRA LARGE" size. My monitor is set to 1024x768 and I process most of my pics in portrait at 480x640. How do I modify the flash gallery to allow a full size 480x640 image size instead of LR shrinking it down. Thanks for the help.

I've noticed there is a bug in how previews are shown in the gallery. The flash gallery images are actually quite large (you can view them in the "bin/images/large" directory of the gallery). Sometimes it will render them smaller than they actually are in some browsers. Try widening your web browser window until it says it is reloading the image to fit the new browser size. At that point a larger version will show and you can shrink the browser back down to it's previous size and the images will fill the screen better.
