The main window of BatchBlitz consists of four views:
Source, Output, Actions and Preview.
You switch between them by clicking the corresponding icons on the
left.
Source view is where you select the source images for
further processing (i.e. filtering, categorizing or editing).
As shown in the below image, the Folders pane and the Files pane help you browse for source images
on your hard disk. You can drag folders or files from these panes
(or even from Windows Explorer) into the Source Images list.

Output view (shown below) lets you specify where and how
to store the processed images.

Actions view lets you define one or more actions (e.g.
resizing, cropping, adding watermarks, etc.) that you want to
perform on the source images.
As shown in the below image, actions are grouped into three
categories. You can activate, deactivate and comment actions. To
edit an action, you simply double-click it. To remove an action,
just select it and press DELETE. You can even re-order actions by
drag-and-drop.

Preview view (shown below) lets you preview the effects
of your defined actions applied to the demo image.

By categorizing, you group your photos into different folders.
Photos with a common property (e.g. camera model, date taken, etc.)
will be put into the same folder.
As shown below, we categorize our photos by camera make. So the
Canon folder contains all photos taken with a Canon digital
camera.

In BatchBlitz, the Categorize Images Wizard makes it easy
to categorize your photos. You get all done in three steps!

BatchBlitz allows you to directly excluded unwanted images from
the Source Images list. As shown in the below image, the
Filter Files dialog lets you do file filtering with
instantly visible results.

You can also do file filtering (as an action) in a batch task.
More options are supported in this case. As can be seen in the
below image, you can define complicated filtering rules.

BatchBlitz lets you to batch-process your photos using
actions.
In a batch processing task, you simply select some source
images, specify where and how to store the output files, define one
or more actions, and then start the task with a click.
The below image shows the added actions in a batch task:

Actions are powerful and highly customizable. As shown below,
the Add Text action provides a variety of options:
