Thank you Ross, but the right click button only shows the javascript stuff, can´t download the images from the photo plugin or from the newsfeed.

In this case if there's no full-size image photo, you need open the photo in the newsfeed or in the photo section and then inspect element. Click with the right button of your mouse, then inspect element and you'll see an image source. Open it in a new window and save the file

I alredy resolved the issue customizing the code and adding a "download image" button.

Thanks Ross, I understand this is a workaround, I hope 1.6 came with this feature resolved, I am sure a simple "download image" button is no challenge for the OX team!

Alright. I mark this topic as solved then.
