(Metro Theme) Fix Blog "Next Page" feature, remove text from banner section, Image link custom URL

In the blog section, the "Next Page" feature at the bottom only works up to the second page. After the second page, you are brought back to page 1. It needs to scroll through all pages until the very end. The default banner of Metro Theme displays the title in text form. This is also displayed in the browser tab header. I do not want the blog title to display in the banner section as I have uploaded a custom banner. I need it to display correctly in the tab header though. The current workaround is to remove the title so the tab header reads " - Red Dragon Diaries". But it should read "Red Dragon Diaries - Own your ESL adventure" I want to insert affiliate images into blog posts. I have the affiliate banners and links. When I insert the image into a post and identify a custom URL to open in a new window it tries to display the image but does not open a new window. Instead it gives an error message "image cannot be [login to view URL] sure the path is correct and the image exist". However, if I right click "open in a new window" a new window is opened from the image with the correct URL. But this defeats the purpose. It needs to open a new window and display upon single click.
