I need the pictures being linked to every post in the Blog

[StarClown]

What I mean is:
I need the main picture from every post is linked on the post card to the respective post, but I couldn't find the way to do it in the Simple Blog Plugin files.

I assume that I need a custom script to make it happens, can anyone give me a hand on this please?

Thank you.

I haven't looked at the blog plugin and whether it's that or the base template you are using, but on the assumption that every post you make will include a "main picture", I would approach the issue by editing the template to add code to make sure that every page generated includes html code that ensures that main picture will include a link.
