Im trying to do this but I don't know if that is even possible. I have a normal list with that "Add new item" to open a form, is it possible to have an image with a hyperlink that when clicked open the form automatically without the need of changing the page to that particular list
Did you want to create a hyperlink to the "Add New Item" form? In that case you can do so by using the following URL:
Where URL1 is the url to your site, and url2 is url where you want to redirect the user to after they finished adding a new item.
