Download Irfanview from
www.irfanview.com. It is FREE image editing software, and it is very easy to use. If your photos are larger than 640x480, tell it to resize it to that size. If they are smaller, leave the size alone. If they are not saved as JPG format, tell it to "save as" and choose JPG format. That will get the photo size small enough that you can post it here.
Really. Try the Irfanview. You will like it, and the price is right.
If you have any questions, let me know.
