Main Panel
The main panel of the applet (shown above at half size, or click on it for a full size image) contains preview images (1/18 the size of the highest resolution images), and image controls and a control panel to enable selection of image slices. The control panel contains controls for selecting the image type and format, as well as resolution controls and access controls.
Image Type
In the control panel, you should first choose whether you want to view Male or Female images.
The control panel also allows the user to choose MRI, CT or Photo image formats, however currently only Photo (or anatomical) format images are available, and this is set as the default image format.
The image controls display thumbnail-resolution preview slices
and lets you choose an image slice to view at higher resolution.
You can select the type of slice you want by clicking on the image or the
viewpoint name (Axial, Sagittal, or Coronal).
This will highlight the viewpoint name in blue, and the cutting line which
produced that image will be indicated by changing color from red to cyan.
For example, clicking
on the Axial image highlights the cutting line in the Coronal viewpoint,
since this is the line you need to move to select a new Axial slice.
To chose a new slice, click on the cutting line and
drag it to a new position. A new preview image will
appear after you release the mouse button (this may take a while,
since the thumbnail image is downloaded from the Web server).
If you want to view only part of the image shown in the preview, you can
crop the image by drawing a box around the region you wish to view.
You draw the box in the usual way, by clicking the mouse, dragging it
until it is the desired size, then releasing the mouse
(note that cropping may not work on mirror sites).
Once you have selected an image slice that you want to download,
you first need to specify the resolution of the image to be downloaded.
The resolution controls let you switch between
Low, Medium and High
resolution images for loading.
The current resolution is shown in blue.
The adjust buttons (the triangle buttons)
let you fine tune the exact slice number you want, which is shown in blue
for the currently active viewpoint.
Now if you want to see a full size picture of the slice you have chosen,
press the Load Image button to pop up
a new image slice window,
which will display the last image slice you selected at the chosen resolution.

Popup Image Slice Window
The image popup window (shown above at half size) displays the image slice. If the image is larger than the window area, you can resize the window, and also click or drag on the scroll bars to move around the image. If you click on the image, you can also drag the image by sliding your mouse.
Popup Image Controls
Press the Quit button when you finish viewing the picture.
The Download button will transfer the current image to the Web browser (or the image viewer used by the browser) for display, and thus will let you save the image into file on your computer.
If you want to resize the image you can click or drag on the scroll bar on the right. The image is initially displayed at 50% or 100% scale. 100% indicates the full resolution image (i.e. 1:1 scale), and you can resize the image from 25% to 200%. You can also obtain a full resolution image by just pressing the 1:1 button. After you press the Resize button, the window will begin to update the image to the scale you assign (this may take some time). Note: If your computer's memory resources are limited, don't try to enlarge the image greater than 100% or your browser may stop working.
