Effective online display of art images
The most important issue in the online presentation of art images is
the tradeoff between sufficiently detailed images and limitations of
browser screen "real estate". For most low-end systems, running at a
resolution of 640 x 480 pixels, a screen-sized image just does not provide
sufficient detail to do any justice to the painting. Navigational elements
can further reduce available screen "real estate", accentuating the
problem.
The standard design solution is to provide thumbnail images which
link to a larger, full-sized image. The Artchive
uses this approach. Note that the online version of the site does
not automatically display the thumbnails, which for some artists with
one hundred or more images, would be a download of more than 500kb.
Instead, the visitor is given the option of viewing all of the thumbnails.
The thumbnail image is effective at providing a point of reference
for the viewer when later confronted with the full-sized image, which
must be scrolled in order to be completely studied.
In scanning images, I have evolved an approach of providing separate
detail images in lieu of a single large scan. Thus, the visitor can
view the thumbnail, the entire image at close to screen size, and
finally a more detailed depiction of a portion of the entire image.
This means of moving from the microcosmic to the macrocosmic provides
an enriched viewing experience of the work of art.
The framed interface of the Artchive sacrifices screen real estate
for serendipity. Often visitors enter the site directly into a specific
artist's section; I want the lengthy listing of names to indicate
to them that there are images from another two hundred or so artists
to explore. Some of the most rewarding feedback comes from visitors
expressing their appreciation for having been introduced to an artist
they had never heard of before.
The Artchive is in serious need of enhancement as far as exhibition
of images. For one thing, JavaScript code could provide a means of
displaying the images by themselves in a new browser window, thereby
maximizing screen real estate. The raw size of the Artchive, more
than two thousand scans, makes coding this sort of update a time constrained
effort. For now, I have offered visitors a number of viewing
tips to help make the most of their screen real estate.
