I can't seem to find anyway to upload images. Have things changed?
Posting images
The images have to be hosted online already. Then click more reply options and select the photograph with what looks like a tree in it.
There's a little button when you're posting that looks like a Polaroid or some little picture. Hover over it and it'll say: 'Image.'
Find the image you want on google or wherever, right click it and select "Copy image URL" or whatever your browser says. Or just copy the image URL from the browser bar if that's all that's open.
Then just paste the URL into the box that came up when you clicked the 'Image' button.
This kind of thread goes here.
