@bueltge Is there a way to add an upload image to this?

This code snippet didn't seem to work for me either. However the tutorial at http://wp.tutsplus.com/tutorials/creative-coding/posting-via-the-front-end-inserting/ seems to have done the charm for me.

Upon further research I found why I was getting a 404. When my form tag field was named 'tag' I would get a 404, as Wordpress has default handling for /tag. Example ... once I renamed it to .. in HTML that solved the issue. Hope this helps.

It worked fine for me when i removed the wp_ounce function. tho, i had to use it as a page template.

I can't get this working either. Could you just clarify what goes in functions.php, and what goes in post-process.php?

Thanks
