I wish we could make it easier
but we dont have bandwidth enough for hosting many pictures. In the near future, each member will be allowed to upload a single picture of thier car. I hope to be able to do more than that later. But right now we are already using than our 4 Gigabytes of alloted bandwidth per month. We are moving the site to a new server eary next month and will allow a single picture shortly after that.
For now, like some of the posts have stated, you have to find a place to host the picture first then you can embed it into any post by using the img vbCode. You can read more about using vbCodes
