Go directly to my Picasa feed. You can grab all of my work at the highest resolution at which I uploaded it.
Remember to only download directly through the main gallery. If you try using the download button after clicking on an image, it just displays a lower-resolution version of the picture. Click on the "Belongs to" link to the right of the page, then click on the image you want. That gives you the download button that actually provides the full resolution image. What a pain.
My Flickr feed is less deliberate than my Picasa. Whereas with Picasa I format and crop photos, Flickr is directly hooked up to Lightroom, so I'll frequently just throw up untouched photos that I think are good.
