Why does it matter? File size can make a big difference in the performace of your pages. For students with slower connection speeds, a lot of high resolution images on one page can really slow them down.

The big thing on images is dots per inch or "dpi". It takes a higher dpi to print clear images than it does to see them on the screen. So you don't need huge file sizes if you're only going to be posting an image to view. Remember, though - if you reduce the size of most image files (.jpg, .bmp, or .png), you can not enlarge them again and end up with a clear print image. So if you think may need it for print someday, store an original version of your image.

Generally, a 72 dpi for a 4 inch by 5 inch image is good for screen viewing.

It's important to note that a file with a 72 dpi, but 40 inches x 50 inches is a really big file. Remember, it's "dots PER inch", more inches, more dots, bigger file. So pay attention to dimensions.

Recommended freeware Screen Resizer:

You can resize images in most image programs. The nice thing about FfastStone is that you can do a whole bunch of files at once and give them a modified name in the process. Also, it converts image file formats. It's fast and easy to use.

Picture Presentation
So do you have a bunch of pictures that you want to show your class? There are so many different programs out there. One that works well is Picture Trail. But there are new ones all the time. If you've used one you like, please share!

Blabberize is a fun way to make still pictures "talk" and is also posted below.

Picture Trail provides you with an embed code you can place right in your course page. HOWEVER, there is a 60 image limit. You can always break it up into separate "flicks" - their wording for the moving pics. See sample below. Note: After a certain period of use, or number of photos stored, picture trail may require an upgrade to their premium account. Micki has maintained 220 image files on their site, and the slideshow below still works with no requirement for upgrade.

Blabberize allows you to take still images, create a moving "mouth" and have the images talk. Lots of possibilities! It's a really fun way to have a still photo of a person (scientist, history figure, a cow) introduce a lesson or topic. The website gets overloaded afternoons because it's so popular! No success in downloading converted video, but the embed code works - see below. Another option is to screen record your blabberize using Blueberry Express screen recorder, Camtasia or Screentastic.

** Finding Images**
As of April, 2011 malware (viruses) were showing up attached to Google image searches (click here for article: Scammers swap Google images  for malware )

So, where can you find FREE images that are in the public domain without viruses attached to them?

Licensing for use of pictures can be tricky. Try these sites. The images are free for use, and may be altered (cropped, colored, pixeled) but should not be sold:

Ookaboo @http://ookaboo.com/o/pictures/ Lots of world culture pictures.

Morgue File @http://www.morguefile.com/ HUGE database of pics! Nicely done - kind of artsy, but lots of simple things.

Free Foto @http://www.freefoto.com/browse/?ffid=0-00-00 A decent site for basic images. Not too artsy - straight forward animals, trees, locations.

US. Govt. Photos: @http://www.usa.gov/Topics/Graphics.shtml A great site for history, science & social studies. Links to several different groups - be sure to check whether it's open to public domain or if attribution is required (just giving credit to the photographer or website) The National Oceanic and Atmospheric (NOAA) phot library is beautiful.

Every Stock Photo:[| http://www.everystockphoto.com/] This site is mentioned many times on the web. The one thing noted, is that some of the images mixed in are from sites where you have to pay a royalty. Micki prefers Morgue file for the same type of images - but if you try this out and like it, let us know here!

Pattern Cooler: http://www.patterncooler.com/index.php?page=2&tag=&PB= Can't find that perfect wallpaper or background for your powerpoint? Then make it on this site!
