ok so seatcupra.net does not allow you to enter pics in threads. ie you cannot load directly to the forum.
Instead there are sites such as photobucket which are places you can upload and
store images.
You can then put a link to an image stored in this way by entering the web link.
There are also web links which have IMG prefixes,. these links automatically open to show the link detail.
This means you can upload to photobucket (others available), then copy the img link, post that to here and then when you view it shows the image.
If you look at some older threads on here, you can sometimes see a RED CROSS instead of a pic, this is where the link no longer works, for example if the image is deleted at the hosting website.
In the case of photobucket when i go into my account and view an image, on the right hand side of the page there are 4 types of links to the photo, one of which is IMG, when i click on this it says 'copied' i then just paste that link on here.
below should show a pic from my photobucket page,
(unfortunate place to have the exhaust pipe)
if you click on the photo below it should open up a new window where you can see the web address. or right click and copy weblink, you can see this photo is from my photobucket account so is not actually held on the seatcupra/net server.
