After seeing people having issues recently with Imageshack, Photobucket, Flickr etc, I've decided to write this guide to help you host images for free.
You will need :
A Computer running Linux, Windows or OS X.
The Internets
DropboxSome cool pictures.
Guide.
Download and install Dropbox on your computer.
You can either google for it or use the link I've provided above.
I'd appreciate it if you used my link, as it classes as a referral and I get 250mb more space each time!
Once Dropbox has installed, you will have a folder on the computer under Documents.
In here you'll see a folder called Public.
Drop your pictures in there, and you'll see a blue circle. Wait until this goes green, then it's synchronised with Dropbox online.
Right click on the image, go to Dropbox, then public link.
Paste that link on the forum using the usual img tags, and you have free hosting.
