How would I go about making an image's file size larger? Should I use certain colors/patterns or what?
I'm trying to make an obnoxiously large image that will take an extremely long time to load. Pic somewhat related, I actually have it up to 50k pixels tall now, but it's still only 700kb in size.

you gotta add more "data" to it. more colors, filter, shit, anything.

i think changing the compression could be more faster, or maybe some steganography method -link below

*way faster

if it's lossless, pure noise is theoretically incompressible, and will thus have a good chance of being large. otherwise, just add a shitton of metadata or something.

Why?

GIF is a bad choice since it uses some techniques like color mapping to reduce file size (every pixel maps a value to a predefined pallette).
This is also how gif does transparency.
PNG on the other hand uses separate 'channels' (think of them as layers with blend modes) and does not uses gif's color palette technique.
Save that inage as a png that supports transparency, and make sure not to save it as interlaced and it becomes huge.

copy image.jpg + win_10.rar annoyingimage.jpg
Would that do the job? It'd certainly take a while to download

>pure noise is theoretically incompressible
except that image you have is not noise at all, that's a simple repeating pattern.
also pure noise that is generated by a computer isn't really pure noise.
also learn about how compression works, psds are compressed by combining groups pixels sharing the same color value data across individual color channels. the more unique colors you have, the larger the file.
