Heh heh, Paint... I just wanted to know how much thought and work you would have to go through to do something as simple as this. And by the way, you can download the same open source software for Windows to do this conversion job, but the point is, Windows is like buying a car from the dealer only to realize you still need to buy wheels, doors, windows, etc. But hey, the dash board sure does look pretty. Say you had 1000 images to convert, how long would it take you?
Just to convert the images, not the URLs in the HTML I would:
for i in `find /var/www/html -name '*.jpg'`;do convert $i ${i%%.jpg}.png; done
I'm sure you will make fun of that command and brush it off as cryptic and difficult. But for me it took a total of about 5 seconds of thought and it will search out and convert every JPEG file to PNG in any subdirectory under my web root. And there are a hundred different ways to do something as simple as this in UNIX, someone else would have probably done it differently. How long from the point of being posed with this simple task did/would it take you to think of a way to do it. Sure you could have used paintbrush, that should only take about 3 man weeks. And it could have been any of a 100 graphic formats, or manipulated the images in many ways within the same command.
Sure, you could use Paint but that is like using a spoon to dig out a hole for an in ground swimming pool. I would rather use a back hoe.
By the way, the open source package that you can even use in Windows is called ImageMagick, which is a VERY robust graphics package for image manipulation. You might want to check it out. It's included in every distro of Linux that I am aware of.
Now, for question number two:
Starting with a basic installation of Windows server (you pick the version) set up a print queue capable of creating PDF files from any printed documents (could come from Word, Excel, Internet Explorer, any Windows app). The resulting document should be emailed to the user so they can then use this less proprietary document to email to clients or use on web sites. How would you perform this task?
