TGPX includes a web-based thumbnail cropping utility that you can use to create preview thumbnails for your galleries. This web based interface allows you to select the image you want to crop as well as the area of the image you want to crop. This document will describe the basic features of the thumbnail cropper.

There is also a screencast showing the main features of the cropping interface.


When the thumbnail cropping window first appears it will scan the gallery to grab the thumbnail images it finds. As the thumbnails are downloaded, they will begin appearing at the top of this interface.

Once all of the thumbnails have loaded, you can click on any of them to select that image as the one you would like to crop. If the gallery is a picture gallery, the full sized image will be downloaded from the gallery and displayed for you to crop. For movie galleries, the thumbnail image that appears on the gallery page will be used for cropping.

After you have selected the image to crop, it will be downloaded and displayed below the thumbnail selection area. You will be able to click and drag your mouse inside the image to select the cropping region. You can resize the cropping region by clicking on the white boxes in the corners and dragging your mouse. As you adjust the cropping region, the preview to the left of the image will be updated showing you what the final thumbnail will look like. Note that the preview is low-quality, and the actual generated thumbnail will appear better than this quick preview.

To create the actual thumbnail, double click your mouse inside the cropping region. This will load a new page where you will see the finished thumbnail.

Keyboard shortcuts

When you are adjusting the cropping region on the image, there are a number of keyboard shortcuts you can use in addition to using your mouse. Those are:

This feature also has an automatic offsetting of the crop location depending on where you click your mouse on the image and the orientation of the image. Those are:
