Too bad, how about you try to make them?

What images, and where? This issue is vague

Oh no, would you like your money back?

Not an issue.

Not necessarily a non-issue. If there are outdated screenshots on official pages somewhere, they need updating.

lol wtf

Try posting some screenshots or list specific blocks that aren't accurate and I will be sure to update them.
All of the images on the CurseForge project page shown in under the image tab are up to date.

They don't look very outdated to me:

Sounds like slycoolgamer is complaining that there are shaders in the pics, making them look different from the pack without shaders.
They complained in the official curseforge post as well.

How is this an issue with the resource pack?

@CyanideX how dare your minecraft look better than mine
