Any chance you can integrate the built-in Wordpress uploader into your forms? This would be very beneficial for user generated content. Example - user creates post:
1. Adds title
2. Adds body content
3. Uploads multiple images via uploader - and [gallery] tag is auto-added to the post.
Trying to create a way for users to be able to add posts from the front-end, but most will be doing so specifically to upload multiple images.
