Images resolution issue

[Alessio]

When I insert an image or an object in my slide using Presentation HD the resolution of the images drop sensibly from the original files.
Even the resolution of lines and shapes created with the app are very low.
How can I fix this?
How can I add to my presentation High resolution images and objects?

I wasn't able to reproduce the issue you describe...
Have you tried saving the Presentations file as prdx or pptx and then opening it in your computer?
Are they low res at the PC too?
