PHP - wysiwyg style image upload?

I am rolling my own blog framework, mainly to learn how everything works.

I would like to be able to upload an image while typing my post (and be able to insert the image's tag without refreshing开发者_高级运维 the page).

Basically, the goal is to be able to embed an image with ease similar to that of a wysiwyg editor.

What is a step in the right direction?

Youll need to look at "ajax upload" techniques. If you google that term you should find various examples. The most common way is to use a hidden iframe to send the data.
