High resolution/Low resolution.

 Today, I used Photoshop to put high resolution images onto a USB pen drive. This is done by changing the size of the file. The larger the file, the more pixels per square inch and the more information is on the print. 

The same is done by creating low resolution files. Any file (according to research) under 300 pixels is low resolution. 

Using this application would benefit the user who is sending an email for example and the file size is too large for the email to handle. If the file size is decreases, the image can be seen by the recipient. You may loose some image quality but at least the image can be viewed.
