The image of the thubmnail is the whole screen. So if you use just a small part of you screen for your construction, the thumbnail will be small. In the construction this can be OK, otherwise you wouldn't be able to move objects in the screen.To get larger thumbnails, make a screenview of the crucial part of the screen and use it to change the image as mathmagic shows.

Great! I saw some of your works on arbelos in resource. Which way did you use In setting the thumbnail of your applets?

You can use any image for the thumbnail of an activity. You open the dialog that mathmagic showed in his screencapture as follows:

- Click in the upperright corner of an activity on the edit icon.

- Then you'll see in the lowerleft corner of your screen the option to open the activity settings.

- Click in the dialog on the button Change Image and browse in the maps of your computer to select an appropriate image.

If you want to use the construction of the applet itself (but enlarge it) use a screencapture program to select the part of the screen you want to use as thumbnail and save it on your computer as an image (choose png as type). Then you can select it in the Activity settings as explained above and shown in the screencapture of mathmagic.
