Boxedit image loading issue

[crashtestman]

Hello,

I tried to load a custom image in Boxedit but had an error related to the size of the image so I tricked Boxedit code in order to make error related to size and data offset inactive.

But well here is the result :

And here is the file I tried to load :
https://files.fm/u/wzwbsstg#_
Or
https://send.firefox.com/download/691e8a7ce2/#vHBtzLAZ4gLY_GO3W3pkcA

I think my BMP file is not right, but cannot find what is wrong.

Thanks a lot for your help.
