Image Sizer is an easy to use tool to resize photos, in order to send them by email. It offers a WYSIWYG interface, that lets you select from different sizing presets, and displays file size and download times for the original and resized image. You can then send the optimized photo by email, without changing your original image. Additional features include color and brightness adjustments, image cropping, rotation, red-eye correction and several image effects. The program also allows you to add watermarks to your images, and can be used to upload images to an FTP server. Image Sizer is easy enough to be used by non-technical users.
Examples of use
Photos to e-mail (e-mail function built in)
Photos to upload to your own website (ftp function built in!)
Auctions item images, there is always a KB size and dimension size limitation in what they will let you upload (e.g. E-bay).
Forums boards, again there is a KB size limitation in what they will let you upload
Webpages, we all hate waiting for badly compressed (non compressed) images!
You can even (if needed) change the WIDTH and HEIGHT of a picture in proportions

Image Sizer is a shareware application that was born out of my own need for a very quick photo resizer/reducer (and image sizing) software in order to be able upload photos to the net or send to family members. After telling some of my family and friends about this, it instantly became apparent that they needed the same thing! With the help and spec of my family members we created this photo resizer for the non technical user, that allows you to resize images fast and with no knowledge of image processing. Size your photos and images instantly with a WYSIWYG view of the new photo/image loaded!
