thumbnail with "readmore"

i am trying to make a thumbnail with a picture and it should have a “readmore” option to have the whole post . (there is a picture in my post).
In my code when i have
<?php the_content_limit(400, “[“.__(‘Read more’));?><div style=”clear:both;”></div>
then i only have a “readmore” option and picture goes away , but when i take away limit 400 and make it look like this
<?php the_content(__(‘Read more’));?><div style=”clear:both;”></div>
then i have a picture but i see the whole post without “readmore” option. i want to have a thumbnail next to a short version post with a readmore opion.can anyone help ? thank you
