-If you'd like to peek at, e.g., ``large.bmp``'s headers (in a more user-friendly way than `xxd` allows), you may use a program called `peek` in the staff solution sandbox. Perhaps better yet, if you'd like to compare your outfile's headers against those from the <<staffs-solution,staff's solution>>, you can copy the files from the link:https://sandbox.cs50.io/aa2c48ff-2520-408a-9951-2b9da0934399[the staff solution sandbox] by following these steps.

-Back in the IDE, highlight `~/pset3/resize` in the file browser, then choose **Upload Local Files** from the File menu, select the `staff.zip` file on your computer, and click **Open** to upload it to your `~/pset3/resize` folder. Click **Close** in the **Upload Files** dialog box.
