Hi, Karyn,
I've learned not to spend too much time tweaking my Image tab -- I like the ever-shifting feel of it. But I do go through the first few pages, every so often, to be sure that nothing stands alone. Small clusters (or large ones, if I've recently posted a series) work well -- a grouping of abstracts, a trio of kaleidoscopes, a few fractals, a clump of photographic art pieces. I guess I go for the Buddy System. :-) I've been thinking about alternating -- Images one week, Galleries the next -- for my opening page. That idea is still in Mulling Stage.
BTW, your current Images page is gorgeous -- wonderfully cohesive without being matchy-matchy. The spikes of red on that page are everything!
(You won't be surprised to hear that I consider 'matchy-matchy' to be a silent killer . . . just like routine.)
