The easiest thing to do is turn down your digital cameras resolution. We throw away 70-80% of the pixels from new digital cameras after you upload the image anyways. So it makes sense to have the camera take them at a smaller size which means the file you upload can be up to 10x smaller.
On a Canon digital camera it's quite easy. Click the "function set" button. Click down until "L" then click to the right until you get 1600x1200 or similar resolution. Then press function set again. I'm sure other camera makers have a similar way to change the camera into a lower resolution mode.
What that does is changes the file size from something like 2-3 megabytes to 200-300k bytes, which is 10x faster to upload.
Alternately you can take them how you are now an then use a free program such as irfanview.com or Picasa on your desktop to resize them. That's quite a bit of work though compared to something that would take a few seconds to change on your digital camera. Consult the manaul for your camera on how to change the resolution. I'd recommend take the pictures at about 1600x1200 mode.
