Wrote this for another car club forum, may as well put it on here:
TO POST A PICTURE THAT IS ON YOUR COMPUTER
First, you need to open an account with a photo hosting website such as www.photobucket.com.
then, upload the pictures from your computer by clicking “browse” which is on the right hand side of the page.
when you have found the picture you want to upload, double click it and it the filename will appear in the box next to the “browse” button. click “submit” under the box where your pictures filename is shown.
when the picture has uploaded, you will see a smaller version of the picture below. Below the picture, there are three boxes with text in them. copy the one that has “Img” next to it, and paste it into your reply box on this forum.
the picture should now appear.
if this doesnt work, you have done it wrong. re-read the instructions and try again - this will work.
TO POST A PICTURE THAT IS ON ANOTHER WEBSITE:
Right click on the picture and select “view image”
the image should be shown on a white background.
copy the address that the image is at.
now click the button that has **Img **on it in the thread reply box.
paste the copied address into the reply box after the **""
then click the Img* button, and this will give ""**
when the message is submitted, the image will appear in the post.
should save a few threads a week
