How do I put a link to a screenshot on my homescreen? I have a screenshot of my university timetable I want to be able to easily access on my Android phone. How can I create a link to this on my homescreen?
You can try this widget : Photo Widget, which allows you to put images on your home screen. Or the application Evernote but it is a bit heavy for what you need however this app is very useful.

Hope this will help
