There are the following things that you may have to know:

Hello everyone,

A few weeks ago the first version of Image Resizer for BlackBerry 10 released.

Sometimes we need to have an ability to resize pictures or photo to upload them to internet services or send via email, but there is no built-in feature to do that. So I decided to develop a small utility to do that and submitted to BlackBerry World.

It was released on 18th October, and on Friday, October 25, I got a BBM message from my friend with link to Crackberry. I was suprised! Crackberry added Image Resizer to their weekly app roundup. It’s amazing, because I have posted no word at blogs and forums about this application.

So download the app and enjoy. It is absolutely FREE!

So I would like to share the code here.
