  <title

  <para
>Selecting <guilabel
>View Thumbnails</guilabel
> in the browser, you get to a thumbnail overview of the images currently in scope (or all images if no scope have been selected). An example of this can be seen in <xref linkend="fig-thumbnailview"/> below. The size of the thumbnails can be configure simply by dragging the mouse with the middle mouse button down (try it is really cool).</para>

  </figure>

  <para
>In the thumbnail overview you can reorder your pictures by dragging them around with the mouse. For the date bar to work properly you should, however, aim at keeping your images sorted at all time. Sorting you images can be done by selecting all images, and choosing <menuchoice
><guimenu
>Images</guimenu
><guimenuitem
>Sort Selected by Date &amp; Time</guimenuitem
></menuchoice
>. The sorting will not reorder images which has the same date and time, so if you have say 100 images with the date 1992 (i.e. no month, no day, only year), then you may move them around, and their individual order will stay unchanged after a sort.</para>

<para
>Slepen van een afbeelding uit de viewer naar de achtergrond stelt de afbeelding in als de achtergrondafbeelding van uw bureaublad.</para>

  <para

  <para

><guimenu
>Images</guimenu
><guimenuitem
>View Selected</guimenuitem

><guimenu
>Images</guimenu
><guimenuitem
>View (in new window)</guimenuitem
></menuchoice
> to get the images loaded into a new viewer. If you press <keycombo

></keycombo

><guimenu
>Images</guimenu
><guimenuitem
>Run Slide Show</guimenuitem

><guimenu
>Images</guimenu
><guimenuitem
>Run Randomized Slide Show</guimenuitem

  <para

></menuchoice

  <para
>There are three ways of deleting an image in &kphotoalbum;, namely move to thrash, delete it from the disk - which means that it will be permanently gone - or tell &kphotoalbum; not to include it. In the latter case, &kphotoalbum; will never show the image again, but it will keep it on disk. This is useful if there for example is <emphasis
>thumbnail images</emphasis
> stored among your images. This thumbnail image would contain an overview of all the other images, and would thus be useless in &kphotoalbum;, but for other application, say a web browser, it might be needed.</para>

<sect1 id="sect-offline-mode">
<title
>Offline-modus</title>
<para
>There is a constant battle going on between data growing, and hard disks getting bigger. If you have a large number of images, you might find yourself in the middle of that battle, not having enough hard disk space to store all your images. In that situation you might choose to put some of the images on CD's. An alternative scenario might be that you are going on a business trip, and want to bring your images with you, but do not have the 20GB disk space requires for that purpose.</para>

<para
>&kphotoalbum; offers a solution to that problem, namely that it allows you to use it, without having the images available on disk. You do of course need to have them available at some point in time for &kphotoalbum; to realize that there are new images for it to index. <xref linkend="fig-offline-mode"/> shows &kphotoalbum; when it is not capable of finding all needed images on the disk.</para>

<para
>Images which have the corner cut of (that is images 1-4) are not available on disk. Thumbnails are, available for images 5-9, even though the images are missing from disk. Therefore &kphotoalbum; can show you the thumbnails for these images but you cannot view them in the viewer. (We used to cut of the corner of thumbnails to indicate the image is missing from disk but that feature seems to be currently broken.) </para>

<para
>As you can see, this feature requires you to copy files in and out of your directories, &kphotoalbum; does not have any support for asking you to insert the CD you labeled blah blah. Thus please forget about this feature if you are the kind of person who do not like messing with files etc, and instead simply ensure to buy hard disks that is large enough to always store all your images.</para>

<title
>Privacy</title>
<para
>Some time ago my girlfriend and I brought my laptop with us on a visit to my parents in law, to show them the images from our most recent holiday. &kphotoalbum; turned out to be a great success, and it didn't last long before my girlfriends little sister seized the laptop and started browsing around on her own. Unfortunately it didn't take her long either to get to some, let say unfortunate, images of me from my youth, and they all had quite a bit of laugh on me. That episode inspired me to add a new feature to &kphotoalbum;, namely privacy locking.</para>

<para
>In the <guimenu
>Images</guimenu
> menu you will find a sub menu called <guimenuitem
>privacy</guimenuitem
>. To get some privacy, browse - while you are on your own - to the images that you want to keep private, and select <guimenuitem
>Lock Away Current Set of Images</guimenuitem
> from the privacy sub menu. Alternatively you may browse to the images you want to limit your little sister to see, and select <guimenuitem
>Lock Away All Other Images</guimenuitem
>.</para>

<para
>Now you have specified what to hide away, and once you hand over your laptop to your little sister, simply choose <guimenuitem
>Lock Images</guimenuitem
>, and your sister will not be able to see the locked images. When done you may unlock them again using <guimenuitem
>Unlock</guimenuitem
>.</para>

<para
>It is possible to specify a password that must be entered to unlock the database. In the <guimenuitem
>privacy</guimenuitem
> menu, simply select <guimenuitem
>Change Password</guimenuitem
> to set a password.</para>

<para
>Don't get fooled to believe that this will help you hide away images for good. First the images are still on the disk, second, anyone with access to the <filename
>index.xml</filename
> file that &kphotoalbum; uses can read the password in clear text and optionally delete it. This feature is only meant as a protection against someone sitting with &kphotoalbum; unintentionally getting to your private images.</para>
