If you have a lot of images of your artwork on your website, it might be more user friendly if you divide your images up into small manageable groupings.
Dividing your work into portfolios serves several functions:
First, as I mentioned, it makes the groupings of images easier to deal with. Don’t make all your portfolios contain so few images that the user has to keep changing portfolios to see them. But if you have a large number of images, say 50 or more, it might be time to start thinking about how you can break them up.
Second, it allows you to spotlight the various types of work that you do and as a result target the visitors who may be interested in that particular type of work.
For example, say you are a landscape artist and all of your images are in one group. A visitor comes to your website looking for a seascape and starts to browse through your portfolio. You do paint seascapes but they are at the end of your portfolio, and after browsing several pages and seeing nothing but desertscapes the visitor leaves. It’s not that you don’t have what he/she is looking for, it’s just that it was too hard to find.
So how should you arrange them?
Some ideas for organizing your images include:
By subject matter: landscapes, portraits, still-life, abstract, etc
By distinctive lines or series: earrings, necklaces, bracelets, etc
By media: paintings, prints, sculpture, etc
By color: color images, black and white images, or even reds, greens, blues
By theme or feeling: portraits of children, historical portraits, equestrian portraits, etc
or any combination thereof.
Of course there are all sorts of other options. It all depends on your own personal preference and your artwork. Have fun with it- make it interesting.
