After several hours of looking into this and trying out many upload/preview scripts (which I got working just fine by themselves), I'm concluding that I wont be able to do this very easily. The problem is, in order to get an image preview, the image must first be uploaded to the server, there is no way around that. In order to upload the image, a
<form> must be used. But since the
item-post page is already a form itself, I can not simply include a new form within the existing from. So the only real way to do this, is to integrate such a feature into the core of OSClass, which I'm not about to attempt at this time.
All in all, the current upload method works just fine. And with my plugin, once the pictures are uploaded, you can do anything you want with them. Sure, having an image preview during initial upload would be nice, so hopefully in the future this will happen.
My next step in development for
Picture Director are some additional picture editing features, such as the ability to
crop a photo, among other things. I'm open to any suggestions in this area!

What do you think would be a useful feature for
you?
