Picture Files Size
I am trying to reduce the space some pictures take up on my MacBrook Pro.
Typically, I transfer pictures from my phone to my camera. My phone defaults by taking really large pictures--which I like for detail.
But I don't need all of them to be so big on my hard drive. However, when I use Preview to adjust the pictures (usually to 640 x 480), the picture file size says it is greatly reduced (from like 3 MB to around 200 kb). However, the storage space on my hard drive doesn't increase. In fact, it continues to decrease after I supposedly reduce the file size of these pictures.
Can someone please help? Thanks.
