If you join a free photosharing website like Imgur you can copy and paste to here.
I am on imgur.com and this is how you do it. First join then you will get this home page...
Now hit new post and drag your photo onto the page, and it will store inside your page.
Another method is to just drag your photo onto the home page.
Here is my example of an ebay photo dragged in which is in now on my page, and then you just click copy (BBcode) as show, then paste it into the car forum. To paste... Right click mouse to find paste and then paste in. It is very easy once you get the hang of it. Cheers Colin.
Best to keep photo sizes to a reasonable size like 1024 x 768 and preferably a JPEG or JPG as BMP is quite large in storage.
