// name (and path) of the original image that you want to resize (don't forget the path)
// name you want to give to the thumbnail (again - don't forget the path)
// Wanted size - only the HIGHER value needs to be entered.
//Let's say you have an image that is 1000 x 500 pixels and you need a thumbnail that is 100x50 pixels wide.
//All you enter into "wanted size" is 100. Class will calculate by itself what is the other number (50 in this case).
//Code checks if the image is vertically or horizontally oriented, and applies the "wanted size" to the higher value
//(width if the image is horizontal / height if the image is vertical).
// Report - tells the class whether or not to display the progress report
// 1 if you want to display the image data (old file size and pixels, new file size and pixels etc...)
// 0 if you don't want any text to be displayed - just silent thumbnailing.
