Hi,

I wanted to add the following text (written by Boerjrn Kvisli,
slightly modified) to the FAQ.

However, there seems to be some magic behind the scenes:
Trying to edit
  http://www.digikam.org/?q=node/6/edit
just shows
  <h3>digikam FAQ</h3>
and no entries?!

Maybe someone with more knowledge about how to do this
could add the text below as new entry for the FAQ?

Thanks, Arnd

## new Entry for the FAQ.

<h4>Which file format should I use?</h4>
<br/>

<p>
Most digital cameras store images in jpeg format on the memory
card. Jpeg is a compressed format, whose compression causes loss of
quality. Heavy compression may make the loss of quality visible to the
eye. Every time you open a jpeg image, edit it, save the file and
close it, the image is compressed and quality is lost. Lost quality can
not be regained.
</p>

<p>
To avoid this repeated loss of quality you should save your edited files
in a
lossless format. Digikam understands two of these: Tiff and png. In
Digikam it is advisable to use png. Digikam supports the exif data in
png files, whereas (currently) for tiff files, exif data are lost.
So the recommendation is to save any edited files as png.
</p>

<p>
You have now finished editing your photos and are content with the
results. Should you keep the png-files or convert them to the far
smaller jpeg files for storage?. If you are very concerned about
storage space, you can do the latter. You could, however rather keep
the lossless png files and only create jpeg copies in the moment you
want to take your images to the print shop, send them by email or post
them on the web.
</p>
