Back when I had a photoblog, the absolute most popular image was of a blue tie-dyed t-shirt I made in the spring of aught-two. Since Google hasn't purged that picture from its index, I'm still getting hits from people trying to find it. So, by popular demand, here are a few tie-dye photos in popular desktop screen sizes.
To use these as a desktop background, click on the thumbnail to download the picture to your web browser. Then right-click on the picture and select "Set as desktop background".

What this means is that you are free to use them for any noncommercial purpose - your personal web site, your computer background, whatever - but you MUST give me credit. If you use them on a web page, that means providing a link back to this page, or to the home page of greengabbro.net.
To use the images on a web page, please save a copy and upload it to your own server. If your server doesn't allow you to upload your own images, I recommend finding a service such as Photobucket to host the pictures for you. Attempting to call the pictures directly from this server will only cause you pain and sorrow.
