Can't insert a photo

Hi. I wanted to insert a photo into my New Post, but I can't. When I click the 'Insert Image' button, I can choose the photo I want, but I can't insert it. Is there anyone who can help? Otherwise I'll just leave it for now.

I just looked at the inserting image thing, and you could do this;
click on 'Host an image' and upload the picture you want.
Then there should be 3 URLs in the box where you uploaded the picture.
Copy the second one (the one under 'image' - right click and hit copy, when I hit the little button thing it didn't work for some reason)
And paste it into your post - and it should work

Thanks Helena; will give it a go!
