Check your image resolution. It's possible that you scanned it at 150dpi or higher. Images for screens only needs to be 72dpi. You should be able to change this in your document settings.

Make sure when you save your images, they are *.jpg or *.png, and use the compression settings at large or highest quality. It should definitely not be 2500mb unless you are sending something to print, even then that's a bit ridiculous. Save it as a separate document.

Generally I upload files to this forum no bigger than 1000px in width (usually 800 if I can help it).
And a tip, if uploading for instagram, it doesn't need to be any larger than 1200x1200 pixels.
