Can't say that I've ever had any problem attaching photo's in sales.
But I do try to use a plain background, sheet of paper or rubber mat to reduce the file size.
ii take a normal picture then drag in into this app and it shrinks it to a very small size with no image loss , so you can post in classifieds, easy peasy
just google. https://compressjpeg.com/

Assuming you're on Windows, just open the image in paint and select "resize" - pick your new size and save.
