This most likely uses StudioService.PromptImportFile which can be used like so:

local StudioService = game:GetService("StudioService")

-- Imports the File, with a .png and .jpg filter. This function will yield until the user selects a file, or cancels the prompt
local file = StudioService:PromptImportFile({"png", "jpg"})

-- file can be nil if the prompt was cancelled or if the file was larger than 100MB, so have a check for when that occurs 
if file then
   -- outputs the imported file's temporary id
   print(file:GetTemporaryId())
end

Keep in mind that PromptImportFile is PluginSecurity, so this can only be used from a Plugin or the Command Bar so running this from a normal script will cause an error.

Files also have a function called GetBinaryContents, which returns the raw binary of a file.

If you want to use buffers then you can use buffer.fromstring with the binary contents.

local StudioService = game:GetService("StudioService")

-- Imports the File, with a .png and .jpg filter. This function will yield until the user selects a file, or cancels the prompt
local file = StudioService:PromptImportFile({"png", "jpg"})

-- file can be nil if the prompt was cancelled or if the file was larger than 100MB, so have a check for when that occurs 
if file then
   -- Gets the raw binary string of the file
   local binaryContents = file:GetBinaryContents()
   -- creates a buffer from the string above
   local imageBuffer = buffer.fromstring(binaryContents)

   -- code to mess with the buffer as you wish, using the buffer library
end

I assume this is what you mean by that.

Sorry. I mean upload image to rbxtemp with buffer. :pray: is this possible.
Or its possible to create “File” Instance

I’m sorry to disappoint, but Roblox does not have a way for us to do something like that.
File instances can’t be created with Instance.new() either, they’re only returned with the PromptImportFile(s) functions.
