I am a person who wants to make data small. So I usually resize my digital photos to be 640 by 480. I think the size 640 is good for smartphone. But this time I resized photos to be 960 by 720. Just let me see how they are fine in resolution as a trial basis this time, and if it is worth doing with bigger data sizes of picture file.
Okay, this is the end of this post. I have to make a lot of PPT slides from now to prepare for online teaching in the coming week. I have no time to take a rest.
