Images can link to a PDF
I created a press page for my client and learned that I can't link images to PDFs. So I added text links underneath the magazine covers - The very first thing my client said when she saw the page was, "shouldn't I be able to click on the image to read the PDF". This is fundamental...
Having more “link-to” abilities to the image element is something we do need to do.
By the way, there’s a trick you should try:
You said you have uploaded a file using text right? so you should click on that link, and then copy it’s URL.
Know that you have a URL, select the Image element, set it to link to a link, and paste the URL. This should make the image clickable, and linked to the file.
Let us know if it works for you.
