I can provide the code for any of these sections if it helps:
Comments (comments.php)
Footer (footer.php)
Header (header.php)
Main Index Template (index.php)
Page Template (page.php)
Single Post (single.php)

Im after a slight ammendment to the grid-a-licious theme and linking.
I want to have, on the main page, just images and a link under it.
When you click the image or link, it opens the post with as normal but i want to have a large extract of text in there.

If i post a large extract of text now it appears on the main screen which i dont like.

Any ideas?
