You'll need to resize the pictures to get them smaller. Really a 100k file is plenty big for web site stuff.
Try going into your photo program and reducing the size of the picture and then saving as a copy (so you don't ruin your original large resolution photo) Use 700 or 800 pixels as a maximum width. Or try changing the resolution to 72 dpi.
It really depends on what photo editing program you have (ie. Photoshop, Paint Shop, etc.) If you tell us what you're using we can probably step you through it.
If you get really frustrated just email them to me and I'll resize.
