Here is some info on posting pictures
There are 2 ways to attach an image
1. When Starting a New Thread or Post Click the button on the Editor and insert the image location of the image that's already online somewhere , Right click the image you want and select copy image location then paste it in the pop up and your image will show on the thread
Now if your image isnt already online you will need to upload it
2. When starting a new thread scroll down and click manage attachments this will allow you to browse your computer for the file and upload it to diesel bombers
Alternatively you can upload your photos to your user album and refer back to it
Hope this helps
