I use Flickr, its much easier to see pics on Flickr 🙂
Sign up (its free) Upload your photos.
Then when you want to add a photo on the forums, you will see a little box with an arrow in it, click on that box, you then have options, you need the HTML/BBCode, Copy the code then return to the forum and paste in the photo code

The code has Flickr’s address on it (see above pic) You can shorten this down by just using the image brackets only, after you have pasted the code just use the delete button to rub out all the URL codes attached to the pic (see below)

Now I know you can see the pictures here, but if you quote my post you will be able to see the image codes I am talking about.
Image codes start and end like this
You don’t need all the other attached stuff. You can also chose what size pic you wish to use on Flickr. Hope that helps
