Excel Image resolution change

[seeker123]

Hi

I have an excel file that in every row I add a picture to in one of the cells.
Pictures are big and I drag them to fit in one cell then I save the file .
The problem is when I open the file I want to be able to drag the picture and see the info on it but the pictures resolution has been reduced and i cant see any thing.

Do you know what I should do if I want pictures resolution not to change?

Thanks in advance
