Do you have an Imageshack, Flickr or Photobucket account? If not, get one.
I use Photobucket.
Upload your pic(s) to their site & when you hover your mouse over the pic, you should see this....
Notice the four options underneath the thumbnail? Left click on the bottom one entitled 'IMG code' & the link is automatically copied. You can then paste the code in your reply box on Hotrodders & you should see the full size pic on your screen, like this... (hope you don't mind me using your pic as reference. I had to make it a bit smaller for Photobucket)
