In the beginning I would simply create a page and insert the images. Then I started using the web gallery option in Photoshop Elements and Photoshop. The latest version of Photoshop, ver. CS2 has several more options than Photoshop 7. I just finished making a new web portfolio of my early sculpture, work done almost 30 years ago (wow I really am getting old).
The images I originally posted on my web site were small so I went back to a Kodak PhotoCD I had made back in 1993. They scanned 100 of my slides and put them on a CD for about $60 back then. The problem was the slides were not in pristine condition and the scans showed every piece of dirt and every hair on them. The images also had color problems. So I used Photoshop to clean up and color correct the images and posted here is one before and after.
BTW - A 30 year younger version of me is in one of the images.
