When To Use .jpg vs. .gif vs. .png

If you work on your library's website, this infographic on when to use different graphic formats might be useful. Tech things like this always interest me (if you're only a little interested, skip down to the What Should You Use section at the very bottom for the summary). (via)

And speaking of image stuff, Here's a List of More Than 30 Free Image Sites That Don't Look Stock-y. Nice-looking free images are always a good resource. (via)

Reference Question of the Week – 2/15/09

   February 21st, 2009 Brian Herzog

I found a picture in Wikipedia that shows a map at four different periods in history. I want to print all four versions, but I can't get the image to stop.

We looked up the map he was talking about on one of the desk computers, and I saw that it was an animated gif file. By repeatedly printing the page at various stages of loading, the patron said he was able to get the first and last frames, but never the middle two.

I've never attempted to print an animated gif, and thought this was an interesting problem. I don't know if there is an official way to do this, but my solution was to simply do screen-captures for each frame, and then paste that into PowerPoint to print.

If you've never done this before, screen-capture is a handy tool - like the name implies, it is a method to capture whatever is displaying on your computer's screen. The display gets copied to the clipboard as an image, and can be pasted into other programs, just like anything else copied to the clipboard. (This is an especially useful technique if you're making how-to instructions [pdf, 297kb] for using software or a website - you can easily include visuals of exactly what your user will see.)

Here's how to do it:

  • Press the [Print Screen] key on the keyboard. That's it, you did a screen-capture. Now paste it somewhere to see what it looks like
  • A variant on this is to press [Alt]+[Print Screen] - while just the Print Screen key copies the entire screen, pressing Alt simultaneously will capture only the active window. This is useful as it lets you size the window to show only want you want, and it also leaves out the Start Bar and other menus or Desktopery

It worked, and the patron was happy - he liked it so much, in fact, that he wanted me to reprint the two maps he printed, so they'd all look the same. He also asked me to send him all four screen-captures as a single file [pdf, 567kb].
