How to upload an image from your computer into a post here
1. From an open post, click on the icon above it that says 'host an image' when you hover over it.
2. Click on 'choose file'
3. Choose your file then click 'open'
4. Click on 'host it'
5. Highlight then copy the bottom address: 'image url'
6. Click on the icon next to the 'host an image' icon, called 'insert image'
7. Paste your copied address into the URL box
8. Click on 'insert'
9. Preview your post, hopefully you should see an image in it! If you do, click on 'send' at the bottom.
You can also use an offsite free Photo-hosting site such as Imgur, which produces a better quality image than using the inbuilt forumotion system. That will give you the 'IMG...' code for your uploaded images, which when posted here, will make your image appear in the thread. I no longer recommend using Photobucket, due to a change in their T&Cs that disallows using their site to host images for use on other websites unless you pay.
