How to Reduce the Size of your Picture

Now and then, most of us may have difficulty sending our pictures through the email. This is because the service provider (e.g. gmail, hotmail, yahoo, singnet, etc) put a cap on the maximum amount of file size attachment we can send at one time. If you have a lot of pictures with high resolution to send, you can simply reduce the file size first. If still in trouble, you can send the pictures in batches, a few at a time. One simple way to reduce your (picture) file size is to make use of the Paint Program in your computer. Note, if you still want to keep your original picture with high resolution, make a copy first and put all your copies (pictures) in one new file folder. With the copies in your new folder, do the following:

1)Place the mouse on the 1st picture, right click the mouse and move the mouse to the selection "Open with"
2) Go to the adjacent menu and select "Paint" program with a left click.
3)With the 1st picture just opened, save the picture under the same file name. This will over-write the existing file and at the same time reduces the file size.
4) Repeat the above with the 2nd picture.
