These instructions are for watermarking images on the command line using the ImageMagick command "composite".  So you'll need to have SSH access to your images.  (To watermark images off-server -- ie., on your desktop in Windows -- check out this list of programs.)

1. Create a PNG watermark image

Using PNG, you can avoid distortion of the watermark when its composited

If your original images are dark, you should use white text for the watermark.  If your images are light, use black text.  Don't worry about shades of the text color for now.  You can adjust how brightness of the watermark on the command line.

I used Photoshop to create a small image with the watermark text, then save it as PNG.

2. Run the command: composite

The full command with options is:

composite \
  -dissolve 80 \
  -gravity southeast \
  watermark.png \
  original-image.jpg \
  new-watermarked-image.jpg

This command applies the watermark image to the original image, and creates a new composite image.  It sets the watermark to be 80% of its brightness, and places the watermark in the southeast corner (bottom right) of the image.

Notes for each element of the command:

Problem / Symptoms

Your Drupal 5.x or 6.x installation is throwing "Page not found" errors for favicon.ico.  (You can see this in Admin > Logs > Recent Log Entries > Page Not Found)

What's going on?

There is no favicon.ico in the Drupal root directory. 

Drupal's themeing system inserts the following line into your website's source.  This is why when you view your site, you see a favicon in your browser, even though there is no favicon.ico in Drupal's root directory.

<link rel="shortcut icon" href="/misc/favicon.ico" type="image/x-icon" />

But not everyone pays attention to the shortcut link in the page head section.  Some browsers (eg., on bookmarks) or websites (eg., del.icio.us) look for http://example.com/favicon.ico directly.  These requests result in a full Drupal bootstrap, only to have Drupal return a 404 and log the page not found.  Wasted resources.

What we want is to avoid Drupal altogether for direct requests for /favico

Solution(s)

A. Quickest fix for simple installations

If you're using Drupal for a single site, you can just upload a copy of your favicon.ico to your site's root directory. 

B. Multi-site installations

However, if you have a multi-site installation, dropping the favicon in the root directory will cause it to be used for all your sites.  That's no good.  To get around that, you can use the following rewrite rules to point requests for /favicon.ico to the real location.

This article provides a step-by-step guide to extending the wireless network range of a 2WIRE DSL/cable wireless modem, using a Linksys WRT54G-TM.

The important bits:

* The router connected to the internet is the 2WIRE DSL modem that was provided by AT&T. It is a popular wireless modem that DSL providers give to their customers. The problem with the 2WIRE modems is their weak signal strength.

[Note: If you just want to try to boost the signal strength of your 2WIRE modem, go to the administration screen and change the. Using a web browser connected to your network, go to the Web based admin panel of the 2WIRE. I found this at http://gateway.2wire.net. You can also try the default IP address of the 2WIRE modem -- http://192.168.1.64. Under the "Wireless Settings" screen, look for the option called "Power Setting". My 2WIRE defaults to a setting of 4/10. You can increase it to see if it helps extend your wireless network range. Note that this doesn't do anything about the 2WIRE being able to receive transmissions from a weak wireless card on a faraway laptop. The power setting only applies to the transmitting (sending) power of the 2WIRE.]

The problem: The 2WIRE's wireless signal sucks. The wireless signal is extremely flaky beyond 60 feet or so. I want to extend it to the offices next door -- about 120 feet from the router, past metal shelving and one concrete wall.

The solution: Repurpose an unused Linksys WRT54G-TM router as a second access point to the wireless network. So the end result is one unified wireless network, using two access points. You basically have to connect the 2nd router (Linksys) to the 1st router, then disable the router functionality of the 2nd router.

Step-by-step Instructions:

1. Using an ethernet cable, connect the Linksys WRT54G-TM to the 2WIRE. DO NOT use the internet/uplink port. Use a regular LAN port on both sides of the cable.
