You can select files using three methods:

  • By selecting the¬†Select Files from Computer¬†option from the attachment menu
  • By dragging and dropping the file on QuikBox Web Chat
  • By pasting a image from the clipboard

After Selecting the file, you will be prompted to add a name and a description to it. After that just press send.

Be aware that the server administrator can block certain file types from being uploaded.
