How to use the picture editing software Picasa to resize your images.

What is Picasa

Picasa is a free software program supplied by Google. build a website

Once downloaded it automatically sorts all the images stored on your computer.  By pre-sorting your images you can easily modify the sizes either individually or in bulk. Other features include minor touch ups, creating collages and sending as an email etc.

If you are looking for a package to simply manage and reduce the size of your images then Picasa is ideal. Alternatively for more editing features we recommend another package from Google called Picnik. Although Picnik does not have the bulk uploading and resizing capabilitie of Picasa it does provide extensive editing tools, inclusion of text and effects.
