If you already know how to make the screenshots and edit them (it's recommended to edit your payment processor email if listed), just upload it using attachment option. I think most forum now support it. It's located below the edit box where we type our post. Browse the file you want to upload and don't forget to add it as attachment (usually there is a "add this file" button). It'll automatically be displayed at the bottom of your post. If the forum doesn't support it, you may use sites like imagehack like others said.
