Image query

Hello all, I have tried searching for the info I require,

I'm trying to upload images to my grow journal, and have uploaded the images to my R.I.U gallery.

I've clicked properties and copied the address link, and added link via add image in my grow journal post, but they do not show.

Would I be correct in thinking my images have to be hosted on a different host in order for it to work?

Could this thread please be deleted, I've worked out how to upload properly! lol
