How do I redirect a non www address to a www address?

leave a comment »

In my case, I built a Flash site with SWFAddress to allow deeplinking. The downside to this was the site didn’t work well if a user used a URL like instead of

If your site runs on an Apache server, you can use .htaccess to redirect all users visiting a URL (without the www) to a URL (with the www). This is the code you need:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^
RewriteRule (.*)$1 [R=301,L]

Put it in a file named .htaccess, upload it to the root directory of your website, and your good to go.

How do I keep image colors the same between Photoshop and Flash?

Change the RGB color profile in Photoshop

Change the RGB color profile in Photoshop

When I imported an image I created in Photoshop CS 3 into Flash CS 3, the colors always used to change. They were nice and bright in Photoshop, but flat and washed-out in Flash.
I finaly found out this has to do with the color profile settings in Photoshop. By default, RGB images in Photoshop are saved with the sRGB profile. Flash however uses the “normal” RGB profile, and this causes the color-change.

To stop this, in Photoshop chage the RGB color profile to Monitor RGB. Images created and saved with this profile look the same in Photoshop and Flash.
You can change the Photoshop color profile under Edit > Color Settings…

What is a good open source online .flv video player?

with one comment

Recently a client asked me to post a Flash Video (flv) on his website. I did a little web-surfing-research to find a nice open-source flv player to show the video. I ended up using the FLV Player.
I liked it the best because of the way it looks (don’t be put off by the green color, this can easily be changed), because of the easy and extensive configuration, and because it’s really open-source (opposed to the popular JW player for example, which is not free for commercial use).

Why do my colors look different when I use the “Save for web” option in Photoshop?

leave a comment »

The sRGB option

The hidden sRGB option (turned on)

When I used the “Save for Web & Devices” option in Photoshop CS3, I noticed the colors of the saved image looked different from the colours of the original. After some web-surfing-research I found out the problem was this: by default, images saved with Save for Web and Devices are converted to the sRGB color profile. Switching this option off solved my problem. The option is hidden in the little arrow button right from the color preset selection menu (view screen-shot).

How can I use the same SMTP server while mailing from different locations?

leave a comment »

When you work on different locations, you can’t always use your ISP’s outgoing mail-server (SMTP server). When you have a Gmail account, Google offers the free service of using their SMTP server for your outgoing mail, no matter where you are. These are the settings you need to change to make it work:

  • Outgoing mail server (SMTP):
  • Use authentication: Yes
  • Use SSL: Yes (some clients call this STARTTLS)
  • Port: 465 or 587
  • Account name: Your Gmail address (including ‘’)
  • Password: Your Gmail password

Note: when you’re using Gmail as your SMTP server but are not sending your e-mail from your Gmail address, by default Google will change the “from” address into your Gmail address (so to the recipient the email will seem to be sent from your Gmail address, and he/she will most likely reply to this address as well). To prevent this, in your Gmail Settings, go to Accounts, and under Send mail as click on Add another email address. Here add the address you want the “from” address to be, and after adding it click on the make default link behind it.
