Resize image file before uploading


for an application I am working on, users need to upload pictures from the mobile phone. The problem is that the files have large sizes and the connection is unstable. The idea is to be able to resize the files from a multi file upload widget before they are sent to the server by some javascript code running on the browser.

PS: I am working on Cuba 7

How can this be implemented?

Thank you,


any suggestion about this?
