Some HTML Links not working

Hello all, I am completely stumped at the moment…

I have various HTML links on the home page of my website that are linked to IMG files. Even though I have copied the HTML exactly the same and entered the correct permalinks to the correct pages, some of the IMG files just won’t link to the page and when clicking on the image it just returns you back to the home page…

Anyone have any idea why this is? I have removed all the plugins and it’s still doing it. Using the premium Graph Paper Press ‘High Def’ theme at the moment

Thanks
Kane
