PHP Batch Picture Zoom Preview related issues

PHP Batch Picture Zoom preview problem?
1 read a picture of a folder.

2 reads the picture into memory, scales it by an algorithm, and generates $image object.

3 next to each picture, create a form, fill in the name of the picture, category and other information, deposited into the database.


3 key is how to display on the Web page ah?

This way can only show a picture ah, I want to read n pictures.
Header (' Content-type:image/jpeg ');
Imagejpeg ($dstimage, null,100);

-------------------------------------------------------
One way is to say:
But it's not written like this? Action inside header (' content-type:image/jpeg '); Imagejpeg ($dstimage, null,100); Do it?
--------------------

Is there any way to do it? Just give me a link to the article. Picture thumbnails and file operations I've written it all.

------Solution--------------------
One way is to say:
That's how it's done, Action=imagepreview. Reads the specified picture file according to the filename parameter
------Solution--------------------
Does not exist in bulk unless a physical picture is generated
