Highlights
* The tool is using high-quality resizing method, where color of each pixel is a weighted average of all covered pixels from the original image. Linear interpolation is used when zooming in.
* The algorithm is optimized to work with gamma-corrected pictures.
* High speed.
Maximum number of images
Picture Resizer does not limit the number of images resized at once, but there are other factors that may impose a limit.
When files are dragged and dropped on the tool icon, Windows Explorer sends the names of the dropped files as command line parameters to Picture Resizer. Windows has a limit on the total length of command line. If the filenames(+paths) are longer than the limit, Explorer will not run the tool and display an error instead.
To work around this limitation, drag and drop entire folders instead of individual files or place your files closer to to the root of your hard drive (e.g. place them into C:\imgs instead of C:\Documents and Settings\YourUserName\My Documents\My Pictures\Vacation\).
