Topic: Picasa2 and picture quality ?

When I use Picasa2 to generate my gallery, it turns down the quality
of the picture, both on the thumbnail and on the picture that shows
in the frame. But I can right-click on the picture and choose "open picture in new windows" and then it shows the picture in good quality.

Porta do not have this problem, but it shows a text in the bottom that
says "powered by Porta" - I don't want this line to be showed.

Some that can help here ?
