I can't help but wonder though - on a website that advertises extremely pagan/wiccan themes, do you think it's wrong or can be misleading to show images like that?
The question is - misleading of what?
A lot of the sites that are more over the top are selling the 'experience', or the 'witchiness' - not a deeper sense of spirituality, religious commitment, thorough magical knowledge, connection to natural cycles, or anything else along those lines.
The sites that are trying to do those things tend to be less graphic-intensive (and the ones there are tend to be more things like photos, graphics that also convey content in some way, or low-key in general.)
The trick for the reader (and seeker) is to learn to figure out the flash versus the solid content - always useful as a skill. I do think there's also an argument about "What image are we presenting to the larger community.", but I think it's a different conversation.
There's an explanation for our local Pagan Pride I wrote a few years ago that works well for a physical event, but not as well for an online setting, but that gets at some of this.
"At Pagan Pride, you may see people wearing a whole range of clothing. Many of us wear what we’d wear any other weekend – casual and comfortable mainstream clothing. However, you’ll probably also see some people wearing ritual robes, obviously Pagan jewelry or accessories, or fun Pagan t-shirts.
Pagan Pride is a time when people can wear these things in public without having to constantly explain what they’re wearing, and some people deeply enjoy this opportunity. In other cases, someone may be preparing to lead a ritual or workshop in which wearing a ritual robe is appropriate (or part of their regular practice) just as specific clothing is part of many other religious traditions."
