Click on the wee tree image, there's 2 options, click on 'from url' and untick the wee box and paste the link from the pic in there.
I see, maybe it's time i got some glasses. But how do ya do it from the images on the computer? This seems to be the best i can do it with said scenario,
To do it from the images on your computer, don't go to the other tab with the box ticked. Use the default one and just upload it. When you're doing them from the web, if you're Googling images, there's an option at the bottom to look for bigger sizes.
Well **** my old boots, that's where i've been going wrong. I always save it to ma computer before uploadin the begger.
