[Scribus] photo quality

[Chris Smith]

Hello,

Are there certain methods which consistently provide the best possible photo 
quality output from a Scribus page?
For example, should one avoid having Scribus resize the photo on the fly by 
using one that actually fits the frame? Will a tiff work better than a jpeg?
Basically most photos I use will be jpegs from a digital camera that get 
drastically reduced in size and I'm wondering what are some of the better 
ways to handle the process. Also are there certain techniques that work best 
for photo reduction for print purposes.

Thanks.

Chris
