Images not showing at previous entries and next entries

Hi,

If you go right bottom of the homepage of the blog, there is a previous entries link and also the next entries link if you go back a page.

The problem now is if i go in from these links, my image is not showing.

My image link that is showing the iamge should be like this:
https://myblog.com/myimagefolder/mypic.jpg

When i go to through the previous entries link, my image URL becomes like this
https://myblog.com/page/myimagefolder/mypic.jpg
and no image appearing.
There is a “page” directory appear out of nowhere.

Is it got something to do with permlinks? i customised the permlinks using $postnew$

Please help.
