Images uploading twice

Can you please share the link to your home page?

It sounds to me like your theme is using your image from the post and making a feature post on the homepage with an enlarged image. Check your theme options and try to remove feature post and see if that double image problem disappears.

Also the other hitch is the heading ‘The Dream is Alive is linked to my webpage (no idea how that happened) and when you go to that page the image only shows up once…strange.

Find if this code is present in your index page

<?php echo $thumbnail[0]; ?>

If so please remove that.

Alternatively you can add this to your style.css

.entry-image
{
display: none !important;
}

Thanks everyone I seem to have it solved now. I tried your solution Citra and it worked. Thanks
