Hi, I get how annoying it is when images just do not show. The root cause is usually Excel display settings or blocked external content rather than the file itself.
First, in file options advanced, make sure Show picture placeholders is off and under display set for objects to show all. Next, try disabling hardware graphics acceleration in file options advanced to rule out a graphics driver issue. open the file in excel safe mode by holding Ctrl while starting Excel to see if an add in is hiding objects. In Trust Center External Content, allow picture and data connections for this workbook. If it still fails, copy a sheet into a new workbook and test, or use File Account Update Options to repair or update Office.
quick checks for me Are the images on the same sheet and not behind cells or set to Hidden in Selection Pane Home Find and Select Selection Pane Are they actual pictures not linked objects or chart backgrounds Did the sender use a format like xlsb or xlsx and can they share one image separately to confirm it displays on your side What Excel build and Windows version are you on and does the file show images on another PC or in Excel for the web
