with the 3 windows phone resolution :
- 480 × 800
- 768 × 1280
- 720 × 1280
that are scaled to :
- 480 × 800
- 480 × 800
- 480 × 853
What is the size for the image that I should use (admit I want to have a full screen image and that I ignore the 720p resolution) ?
480×800 and use <Image Source="..." />
768×1280 and use <Image Source="..." Width="480" Height="800" />
Using a 768×1280 image and scalling it to 480×800 is usefull ?
Thanks for your answer

Yes. You should always go for a WXGA resolution image, and let the OS downscale it for you. (The scale is roughly 1.6).
Also, you should never specify a static width/height in XAML, if you can avoid it.
