Herp Care Software is great software (freeware). I use it for all my herps. It lets you attach a picture to profiles, and you can track weight easily. It can also export the weight and date to an excel document. I like to use that function to make graphs and charts to see how fast some of my Leos gain weight. You can also use it to schedule feeding, but I only use that function to feed by ball python so I can see how many days between each feeding. You can download it at thegeckocam.com, hope this helped. Best of luck to you.
