I use Imgur, make an account, upload the pictures you want, then, go to gallery, press on the pictures, then the picture should expand, on the right side, a list of links should come up, direct link, bb code, I use direct link then press copy. After that go to Formiculture and press the image icon, its the one on the second row, somewhere in the middle. ( Its a square with a picture of a tree in it) When you press on the image icon, paste your Direct link from Imgur and the picture should come out. If it looks big when you upload it but once you post your comment, the size will be much smaller. Hope this helps. (It's better to use a computer for this) (you can also use other providers besides Imgur)
