Pictures won't load fully

So the file for the book is a acsm. And im using the digital edition app on an android phone. I am able to read the text in the book with no problem but the pictures (wich is a must for me to see) wont load fully, so only half of the picture is visible. I'v tried different connections but that dosen't seem to do anything. Does anyone have similar problems or know how to fix it?
