I use Imgur which is pretty intuitive and allows you to edit and such
You also don't need an account either and there isn't the same storage limits you have with tinypichttps://imgur.com/
1)Go to "new post" left hand corner,
2) click browse to upload or simply drag and drop from your desk top
3) Pic will upload and you can click the down arrow on the right hand corner of the pic for edit options and share links.
4) Under "get share links" you will have several options, use the BBCode link for this forum
5) Copy and paste it directly into a post here!
