A very interesting discussion. But I got lost half way.
I also want users to be able to upload a pofile picture (in my case a company logo). It can be in PDF (but preferably other fomats as well).
What javascript code or settings do I need to set then behind the button? That's not clear for me now.
Can someone please help? I would also like to tell the user (by for example a label text or something) that they can only upload PDF and the maximum dimensions.
I am not a programmer, I just want to insert the script and settings in the button label.
Thanks
