Jerry has two options, he can either compress the picture or resize it
Explanation:
Jerry can use a number of photo editors found on PC, Mac or even online. There are two main solutions, he could use a compression software to compress the image, reducing file size without resizing the image, however image quality will be affected as image data would be lost. The other option is to resize the photo, decreasing the number of pixels it would take to store the image, which then reduces file size. This option does not reduce image quality, although some details might be lost if the image becomes too small. There are softwares that combine both, by reducing the size and applying a little compression. One of these tools is reduceimages.com. However, reducing size can be done in software such as Paint, or Office Powerpoint, to more specialized image editing software as Adobe Photoshop.
