hey!! uhhh i'm new to scratch so idk if im doing this right, but i have a question abt HD upload (or js uploading unpixelated pics in general). so basically, i'm making a project that requires me to download a very LONG image and put it on there, resulting in it being very pixelated. i heard from other scratchers that downloading that 1 extension and using HD upload is a great way to unpixelate images and blablabla. it looked like it works when you first upload the image, and the image looks super clear! but like when i save + exit and enter again or look at the project page, it looks disgustingly pixelated all over again. am i doing something wrong?? HELPPP + i dont wanna pay for a website to unpixelate stuff. i'm poor ok? thanks guys! <3

EDIT: yo i can't understand the words u guys are using can u dumb it down a lil for me

Scratch has maximum dimensions on the size of the costume that is displayed and even vector shapes which don't have a “resolution” will appear blurry if made too big. (2048 pixel limit)

Look into splitting the image up into tiles to be uploaded as separate costumes.

Also, the maximum dimensions for a bitmap image in Scratch is 960x720.

Is it possible to name the extension and provide a sample image where the effects are noticeable?
