I am almost there with the form. There are just a couple of things that I need now.
I have a timthumb script on the site and need to get the relative url of the uploaded image, like this /wp-content/uploads/gravity_forms/DSC_0223.jpg rather than http://example.com/wp-content/uploads/gravity_forms/DSC_0223.jpg
The second thing that I need is once that image is uploaded, I need to insert the dimensions of the image into a custom field.
Then the final thing is that I need to insert the relationship between this new post and what categories they have chosen via the dropdown.
Please could you advise on this.
