Why Iron Browser don't download images?

Hello all,

With my browser SRWare Iron I can not download images. 
When I click with the right mouse button on an image and then "save image as", the browser saves a file as follow: "filename.jpg.crdownload" and immediately after browser crashes. 
The file above I can't open at all, even with the Iron browser. 
How I do to download pictures with Iron? 
Is there another way? 

Thank you

I did not find the right solution from the internet
