I have uploaded a booklet I created and I want to share it with people via text. My booklet has a lovely cover image. But when I text the link to someone, it just shows up with a gray square with PDF in the middle and the title underneath. Is there a way to have the cover page of my booklet show up in the text so it's attactive and people want to click on it?
Unfortunately it's not possible to alter the preview for a shared link at the moment. As I understand this would be a desirable feature for you, I've passed along your feedback to our dev team for review in future Dropbox improvements.
Sorry that I can't be of more help with that, but please do let me know if you have any other questions.
