Over the years I have assembled many images.  Many I made, some I found on the web, and some I scanned and modified.  I have placed the ones that might be of interest in several Albums and Zip files.  I believe these are in the public domain. If you believe otherwise, please email me and I will take appropriate action.    

The image albums show the files as thumbnails in groups of 50. Clicking on the name in the "Album" column brings up the thumbnails. Clicking on a thumbnail brings up the full image that can be saved.

However, I recommend using the Albums to decide if you want the images. Then clicking on the Zip file link and download the desired group. The zip's are sized at about 1 MByte, with the largest at 1.3 MByte. They contain the true original files.  The album generator I used converts all files to the JPG format.  For many small icons and some larger images, this increases the size.
