To resize the image and make it smaller you will need to use some kind of photo editing software. The steps used to resize the image will vary according to the software that is used. With most types of software you can ?right click? on the image with your mouse, move your pointer to ?open with?, choose the program to edit your picture with by using a ?left click?, and it should open up with your picture.
Once you have the photo editing software opened with your picture, you should be able to find ?resize? under ?pictures? or ?tools? in the tool bar. Click on ?resize? and then you will have to play around with it and figure out how to get it to the correct size. You could also ?crop? the picture and change the resolution. You don't need to have the picture resolution set high to be viewed online. There are bunch of different ways to get your picture size below 100kb. Let me know if you want more help.
