ImageRefreshApplet2
displays image from given URL and reloads the file
from the URL and redisplays the image periodically
not using any data cached by the browser. If the
file at the URL is replaced by an other, new image
is displayed at refresh time on user's screen.
This make the applet useful for displaying images
from webcams or for display of a large series of
images while saving webside space.
Parameters: "background" background color of the applet as a triplet of comma separated R,G,B numbers from interval [0,255]; unused portion of the applet and the image canvas will have this color. "canvas_width" width of the canvas for image display; applet width should be at least equal max(canvas_width,120) + 4. "canvas_height" height of the canvas for image display; picture is resized so that the best fit to canvas dimensions is obtained while preserving the picture aspect ratio; applet height should be at least equal the height of the canvas + 54. "refresh_time" time in seconds between two image refreshes. "image_url" URL of the image file relative to the applet code base. |

As I am not permanently connected to Internet and change the image file only from time to time, you probably will not see any picture change when the counter shows 0. But you can observe at that time the download activity on the data exchange indicator (placed in Windows at the right bottom corner of the screen). You can also observe the receive data indicator on your modem to light (if it is visible). If you are using Navigator the data transfer will be also anounced on the status line. |
