Continuing the theme of digital imagery and photography, I happened to notice an email go through on an internal discussion group today which had something like 4MB of attachments in the form of photos. As you can probably imaging, the sender was somewhat flamed and pointed to the Image Resizer tool, a PowerToy for Windows XP. Yes, before you ask, I have managed to get it installed and working quite happily under Windows Server 2003 with a tweak to the LaunchCondition value update to VersionNT >=501 using Orca. Purely coincientally, there's also a paper by Marc Saltzman published yesterday about how to use the powertoy which you can view here. It managed to get a 1.2MB image down to well around 80K for me and is very simple to use (right-click, resize)
Download the Image Resizer powertoy directly or find out more on the home page for the XP Powertoys.
