Pixler is a fantastic free image editor showing how powerful online tools have become. Springing to life inside you internet browser t running on both a Mac or PC, all you need is internet access. If you know Photoshop you will find familiar tools in similar places.
You can view YouTube tutorials here.
The following steps illustrate how an image could be improved and resized for online viewing, like an online learning site. The image has a lot to be improved on eg the contrast enhanced (using the Levels tool), cropped and resized for screen viewing.
This image taken on a cloudy day with out a proper background and lighting serves as a the starting point.
Image to be prepared for screen viewing
1.) Open Pixler and the image to be edited.
test image open in Pixler
2.) Enhance contrast. From the ‘Adjustment’ menu select ‘Levels’ use the sliders to set the ‘black and white points’ as well as the balance.
Select 'levels' in the adjustment menu
levels adjusted, note the change in contrast.
3.) If needed use the crop tool to ‘frame’ the object in the image.

4.) Resize for screen viewing. I recommend to set the image to 1024 pixels wide or 768 high. Please note if the width is 1024 but the hight is more then 768, then adjust the hight to 768 even the resulting width is then less then 1024. An image in portrait format might be 768 pixels high but only a few hundred pixels wide.
Select image size from the 'Image' menu
- Image size menu
To save the image, select Save from the ‘File’ menu. I would recommend to change the name of the image to not save over (loose) the original image if you have adjusted the image size (pixel count).
