Tutorial: Your first use of the Application:
Create a new collection, add pictures and organise them

Objective:

In this tutorial you will learn:

Start the application

There are many ways to start JPO which is why there is an entire page on this website devoted to setting it up. Most importantly you need Java. If you haven't got java or have an old version, get it from http://java.sun.com/javase/downloads/index.jsp#jre. You need the Java Runtime Environment (JRE). The other downloads are for those that want to develop Java programs.

The simplest way to start JPO is by clicking on the "Start now!" hyperlink at the top left of this page. This fires up "Java Web Start" which in turn downloads all the bits and pieces from the Sourceforge web site and then runs JPO on your computer.

You will get a warning about the digital certificate. Since this is not a commercial project I am not going to buy a certificate and you must simply click the message away.

The application window should pop up like this:

New Collection Welcome Screen

Adding pictures to your collection

For this tutorial be sure to have some jpg images handy.

Here is what your Windows Desktop might look like:

Now got to JPO and click on the menu File > Add Pictures:

File Add Pictures Menu

JPO responds with a window which allows you to choose the pictures you would like to add to your collection:

tutorial_add_pictures_dialog

On this dialog window you go to the directory on your computer where the pictures you would like to add are locate. In this example they are on the Desktop. In your case they might be in "My Documents", the C:\ drive or a Memory Stick on drive G:\

In the middle panel you see the files in the directory. You can pick a single picture to add by clicking on it. You can choose additional pictures if you press down the Ctrl key on your keyboard and click on another picture. To pick a range of pictures you click on the first one without pressing anything on the keyboard. Then depress the Shift key and keep pressing it down. Then click on the last picture file. All the pictures between the first and last are selected and highlighted.

The options on the right side do the following:

Recurse subdirectories
If this is ticked JPO will open and look for pictures in subdirectories of directories you have selected. This allows you to add huge trees of pictures. You could for instance simply select the C:\ drive and JPO would look for pictures in all subfolders.
Add new pictures only
This tells JPO not to add pictures you already have in your collection a second time. This allows you to loadd all the pictures from a directory over and over again and JPO will only add those pictures that are new.
Show thumbnail
Tells JPO to prepare a thumbnail in the tabbed pane behind the Options. Not very useful.
Retain directory structure
Usually when you add a directory tree of pictures you would like each subdirectory to become a Group in your collection. This option allows you to turn that behaviour off and all pictures will be added to the same group.

Now click add and you should see the pictures in your collection:

The slider in the top right of the JPO window allows you change the viewing size of the thumbnail images.

What's that picture of the Great Aletsch glacier doing on the side like that? Let's rotate it! Point the mouse at the thumbnail and do a right-click. From the pop-up menu choose "Rotate Right 90". JPO will rotate the image and show it upright. Note that JPO did not modify the original disk picture file. That image is still sideways. Use a graphics program of your choice to modify the source picture (and loose quality in the modification).

Organising your pictures by labelling them

Now let's label the pictures. To do this click at the filename underneath the thumbnail and change the descriptions. Note that you are changing the description in the collection and not the picture on disk. The description is specific to the image in it's position in the collection; i.e. if you have the same picture a second time in the collection, in a different context for example, it can have a different description there despite being the same on-disk picture.

Organising pictures with Drag and Drop

To rearrange the pictures, use drag and drop. You pick up a picture by left-clicking on it and keeping the mouse button depressed. Then move the mouse to where the picture should be dropped and release the mouse. To cancel an inadvertant drag operation press the Esc key on the keyboard.

Sorting your pictures

JPO allows you to sort the pictures in your groups by the time you took the picture, the description and some other fields you can populate. To sort the pictures, point the mouse at the folder icon which holds the pictures and right-click. A popup menu will appear that has offers to sort by the different criteria.

Creating Groups

You create a group by right-clicking on the node under which you would like to add a group. In the pop-up menu choose Add > New Group.

To change the description of the group click it to select it and press F2 to get a cursor. Then edit. You can nest as deeply as you like.

Then, drag and drop the pictures to the correct folders and you might have a collection like this:

Saving your collection

JPO saves the information about your collections in xml files on your computer. To save your collection choose File > Save as from the the menu. JPO will respond with a Save As dialog. Since this is a new collection the File > Save would also have brought you to the Save As dialog.

In the dialog navigate to the folder where you would like to create the JPO collection file and give a name for the file. Then press "Save"

Screenshot of the save as dialog

After saving JPO pops up a dialog that confirms the save. In this dialog you can choose that JPO should open the collection you just saved as the first thing it does when the program starts up.

Autoload confirmation screen

Opening a collection

Use File > Open Collection to bring up a dialog window which allows you to locate the collection xml file and pick it.

Alternatively, JPO "remembers" the last few collections that you worked with and has a shortcut to them. Look at the File > Open Recent menu item. You can simply click a recently used collection to open it up.

Open Recent in File menu
