TIFF images are lossless, and popular, but don't display in a browser.
TIFF is also splintered as a file format, talk to a graphic designer,
TIFF has changed over the last ten years, and most apps allow for the
various forms. You might want to start with TIFFs in your xsane
scanner app.<br>
<br>
As an archive, I would use JPG... it's lossy (by combining like
colors), but if you specifically set it to 100%, you should get no
compression. It's also a well defined, cross platform, standard.<br>
<br>
Although Zope/Plone will store any type of image data, only certain
types will display in a browser, and only certain types can be
converted, whether it be by PIL or ImageMagick. I'm not familiar with
PNM files... it may be raw, but certainly not mainstream, at least not
yet... make sure PIL or ImageMagick supports this.<br>
<br>
BTW, you'll probably get better answers on the Plone Mailing List, for
Plone products using Plone & CMF... more folks there will be using
your setup.<br>

when it comes to archiving images, so any help you can give me would be
greatly appreciated.
<br>
<br>
I want to use Plone as a content management system (CMS) my images,
which are currently stored on my hard drive as PNM files. These files
are scanned copies of 4x6 images, and are usually ~6 MB in size. I am
using Plone 2.0.4 with CMF Photo Album/Photo 0.5.0 and pil 1.1.4. I
use the PNM file format for my pictures because it's the "rawest"
format that I can use with xsane (I also use Gentoo Linux).
<br>
<br>
When I upload my pictures in the PNM format to Plone, I'm not able to
see them. I then tried converting the image (using convert) to a tiff
file (since that's also pretty "raw", right?) and uploading it.
However, I'm still not able to see the image in my cmf photo album. I
ended up converting it to a bitmap, and I'm able to see that in my
album.
<br>
<br>
Is the bmp file format considered a "raw" format? I would like to keep
it as raw as possible so that I can use (or at least convert) my images
50 years from now. Is there a better format to use?
<br>
<br>
I'm using plone as my CMS because I want to attach metadata to my
images. Is anyone else using a different free program that works
better than this solution?
<br>
<br>
Thanks in advance!
