One problem my teachers frequently have, but don’t seem to realize it, is how to resize a photo so that when you send it to Aunt Francis it doesn’t cover her entire desktop. This new tool will take care of that: http://resizeimage.org/. You just need to know how to browse for a file, click upload and then email it back to yourself. Easy peasy!
Here is another good tool-screen capture for free! http://www.nchsoftware.com/capture/index.html
