I recently put six of my new paintings on my website--a process that is always delayed a bit while I decide if the paintings are really finished. Then I scan them on a high resolution scanner in order to get accurate images. After scanning and photoshopping, I then go into Dreamweaver to make a page for each painting.
In any case, this process takes time and care--time away from the actual painting. So I tend to put it off until I have that extra time in my day.
Here are two of the six now shown in my gallery of new paintings:
