Image Resizing and File Compression
For Edline pictures need
to be no more than 314 pixels wide (the height does not matter), smaller
than 75 Kilobytes (larger pictures are difficult to display for families
using dial-up modems), and type .jpg, or .gif
Free Resizing Software
IrfanView Free, easy to use and many
graphic features. I really like using
this for photo adjustments. Works with
many formats and can save as icon files. However while it does good for quality for resizing the compression
results are not as good as others since quality is prime concern. Even tested
the several Resample options but no difference in results.
PIXresizer – FREE http://bluefive.pair.com/pixresizer.htm
This is one recommended by the district.
It is easy to use with many options. In fact it is probably the easiest to use.
Nice that allows for different format savings, rotation, grayscale, and Save As
However, the compression is not as good until to get to much smaller sizes. This is due to the default compressions being high quality. The trick to changing is to click on the “boxed” full format name to reveal the compression settings, but seemed to only work with jpeg. The Default is 90. I tried at 50 for the 640 size and it dropped from 107 K to 45 K without noticeable drop in quality. So if you are willing to take the time to make these settings then PIXresizer is the compression winner.
Microsoft PowerToys for Windows XP
Recommended for ease of
At first I was put off by the interface as not Windows standard and not clear on how to use.
It seemed to me only good for batch jobs
preview button on front page the program becomes easy to use even though it does do follow standard Windows menus
I liked that the aspect ratio was automatic and you could select others than 4 x3. Another feature I liked was it showed the document size in inches or cm after setting your pixels. Another good feature was you had four Compression Quality choices. For the chart I used Max quality but high might be acceptable if even lower compression needed. Even at Max quality was one of the best in lowering the KB. Also does watermarks (even images), grayscale, color auto adjust, and creates albums with choices of skins. It takes a little to learn but recommend as great compression and many good features.
Of the programs does best compression result but not easy to use for the general user being not so user friendly.
To open a file need to “Add Image”
There is no Save As, uses Start so be sure to change “Destination settings” to different folder to prevent losing original image as no option to rename
Only effect is “convert to greyscale’ which reduces size even more.

Picasa – I did not find it friendly for the basic user. Not easy to open one image and I could not find a resize so not included.
