Posting in the thread is really, really easy. There are two steps:
1) Photobucket account. I use this for my personal pictures, or ones that I have saved and cropped. After uploading, select the "Direct Link" and paste it where you want.
2) Right click on an image you've come across online (through google or whatever) and select "Copy Image Location". Paste that wherever you want in your message.
That's it!
