如何使用Tasker每日下载Unsplash Source图片并设置为壁纸？

Hey Kevin! As someone who’s tinkered with Tasker for years, I totally get how frustrating it is when tutorials don’t fit your exact needs. Let’s build this workflow from scratch—you’ll have your daily Unsplash wallpaper set up in 5 minutes.

First, let’s make the core task that handles downloading and setting the wallpaper:

• Open Tasker and tap the + icon in the bottom-right corner to create a new task.
• Name it something clear like Daily Unsplash Wallpaper and tap the checkmark.

This is where we’ll pull the image from your specified Unsplash Source URL:

• Tap + inside the task to add an action, then search for and select the Download action (under the Net category).
• In the URL field, paste your target Unsplash Source link. For example, if you want a random 1080x2340 nature shot, use:

  https://source.unsplash.com/random/1080x2340/?nature
  

  Replace this with your exact preferred URL.
• For the File path, set it to a consistent location Tasker can access, like:

  %TaskerDir/Wallpapers/unsplash_daily.jpg
  

  This saves the image in Tasker’s dedicated folder, making it easy to find later.
• Check the Overwrite box so each new download replaces the old wallpaper file.

Now let’s tell Tasker to use that downloaded image as your wallpaper:

• Tap + again, search for and select the Set Wallpaper action (under the Display category).
• In the Image field, paste the same file path you used in the Download action:

  %TaskerDir/Wallpapers/unsplash_daily.jpg
  

• Under Screen, choose whether you want this to apply to your Home screen, Lock screen, or Both.

Finally, we need to make this task run automatically every day:

• Go back to Tasker’s main screen and tap the + icon in the bottom-left corner to create a new profile.
• Select Time as the profile trigger.
• Set your desired daily time (e.g., 7:00 AM) and make sure Repeat is set to Daily.
• When prompted, select the Daily Unsplash Wallpaper task you created earlier to link it to this profile.

• Add a Flash action at the start of your task with a message like "Updating wallpaper..." so you get a quick visual cue when the task runs.
• If you want to add error handling, include a Notify action that triggers if the Download action fails (use Tasker’s built-in %err variable to check for errors).
• For more control over Unsplash images, tweak your URL parameters—you can specify dimensions, categories, even specific photographer IDs to narrow down your results.
