I made this simple tool because I'm too lazy to deal with this on mobile the manual way. 🤷
For the longest time, marking an image as a spoiler on Discord for mobile hasn't been (and as of April 2021, still isn't) a possibility in the app itself.
Instead, you need to manually rename an image to include the text
SPOILER_ at the beginning of the file name. Compared to desktop/laptop systems, this can be a slow/annoying process on a lot of mobile devices, such as smartphones or tablets.
