Subject: Re: What benefit .png over .jpg?
.PNG is not a replacement for. JPG, but instead is a replacement for. GIF.
.PNG files can have transparent backgrounds and are well optimized for
icons, clipart, or other smaller images. JPG is better suited to pictures.

As for the thumbnails, that is probably Nautilus or a image viewer doing
that so that it can cache the preview so it does not have to calculate it
on the fly. Making small previews is an expensive operation, so the system
caches them. If you delete it, the system will recreate them if you
preview that directory again.
