Are there any way to automatically display post image thumbnail on home page? I mean sometimes we add images end of the post, and jump break post. So when a visitor come to blog home page then he/she can see our home page post and under the post title display image. Then he/she click on post title then image display original location, not under the post title? Like this blog -http://blogger-trick-tips.blogspot.com/
That all depends on how everything is organized. You can write a simple PHP script to check to see if it should display an image (database, or a flat file of sorts) then if it should display one, it can search for the image, or you can also tell it which image in the database or flat file. Then, just have it output the image in HTML format. Look up some basic PHP code.
