How do you post a picture to someone elses discussion?

You do it the exact same way as you would do on your own discussions. See the add an image down on the left side? Right there and do it exactly how you do it with your own. *smiles*

You have to reach 500 posts first, before you can do that. The only one's you can add photos at are your own posts, I think that also comes along with the "copy/paste" feature as you break the 500 post count. But you can still earn and upload some photos here, simply go to the "interests" section and there you can add more images on some of the interests you have on your list. The one's that still doesn't have photos in it or those which only have a few, are the one's where you'll most probably earn so be sure to be more descriptive when adding them..

There should be a "add an image" button down in the left corner when you respond. If it's not there it may mean you can not add images until you reach 500. I know you can't copy and paste until then. Welcome to myLot!
