To do this you need to create a picture album to upload your pictures to. Below are some screenshots which show how to do this.
Step 1.
Go to the Pictures & Albums section, either from your personal profile or from the 'Community' tab above
Step 2.
Click on the 'Create New Album' link
Step 3.
Give your album a name and description. You can also choose to make your album public or private at this point (it will need to be public if you are going to link to the pictures in forum posts)
Step 4.
Select the link to start uploading pictures
Step 5.
Start uploading your pictures, you can upload 5 at a time. Once uploaded you can change the caption text for each picture if you want to and also select which picture will become the album cover picture.
Step 6.
You have now uploaded pictures to your new album, to see the pictures within the album click on the album cover. From here you can click on individual pictures to see them in their larger size.
Step 7.
The full size image gives you link text that you can then copy and paste into forum postings.
The above steps created this sticky post, any problems or queries please post here.
