It would have made sense to implement Pellicola's first ever Easter egg during the Easter break, but the idea for it occurred to me only recently. Anyway, after a new photo has been uploaded to Pellicola, the application automatically generates a tim (tiny image aka thumbnail) for it when the photo is viewed for the first time.
However, viewing the photo before it has been fully uploaded results in a corrupted tim. Also, if you uploaded a new version of the photo, the old tim remains in place. In both situations, you'd want to rebuild the tim, and that's exactly what the Easter egg does. Append &t=1
to the URL of the currently viewed photo as follows:
https://hello.xyz/index.php?file=70686f746f732f3343363531392e6a7067&t=1
Press Enter to reload the page and rebuild the tim. Done!
