Just a tiny tip... You can also adjust the size of the image if it's huge...
On the beginning tag [_img] (added _ in the beginning so I can show it, in the real post the _ needs to be removed of course) you can write the height and width attributes and it gets smaller. For example... [_img width=261 height=391] ->
This is the huge pic here: https://s-media-cache-ak0...ef0ff273a22239053e7a8.jpg
Then how to know the new width and height you want the picture to be so you won't mess the proportions? Well, there's a formula on how to calculate it but as I use Chrome, I simply tap the image and choose 'inspect'. When the code opens, I look at the size on the right of the screen (width and height) and adjust the image size by moving the border between the code window and the image. This is a bit tricky though, maybe someone else could explain it better.
