is it possible to encode computation inside PNG files? Lets say i have 2 files of 1 pixel, can you i,e use R, G, B component to do work?

I have no idea if you mean something like pic related (where an image gets saved as a bmp) or something like https://esolangs.org/wiki/Piet

yeah, lets do some math eh?

1920 ^ 1080 = 9.2326633422521553117362172914413e+3545

Did you mean to do (1920 * 1080)^20 = 2.160228462010307e126

no, i literally mean 1920 ^ 1080..

for every X pixel there are 1080 combinations

I'll look into it in the morning. Cool idea.

I think the CS monkey is asking about homomorphic computing with compressed png images.

Do you think maybe the reason why ~90% of my image uploads to my FTP hosting account fail, then Filezilla breaks the connection, then the partially uploaded file "finishes uploading," is because people are putting this sort of thing into my image uploads? When it does that, I wonder the single file upload spread across mutilple broken connections ends up uploading exactly the file I'm trying to upload or if that is indicative of this AIDS?

I'm going to switch to SFTP hosting but I can't until ICANN's 60 days between registrations runs out.

What do you mean exactly? You can encode an executable program inside a PNG (suppose ARGB, you can store 4 bytes per pixel) and then write a program that decodes it and executes the code.

Short answer, definitely yes. You would have to use machine language(lower than assembly) though. Save the image pixel values as machine instructions (computer uses numbers to differentiate between machine instructions).
