What do you guys think about adding pics in general?
I´m thinking of adding a pic, but idk if it wont maybe turn some people off.
When I write, I orientate myself to Hentai manga, so I´d pick a drawn picture to go with it, but I don´t want to scare off people who dislike Hentai...
I think its really dependant on the story.
Some stories revolve around a picture series. The pictures are a companion to the story, and probably lead the story, and when written the story should have the pictures in mind.
Some stories force the pictures in. This can be awkward, it can be distracting, but on the plus side... Who the hell doesn't like a good, sexy picture regardless of the context? Still, this is probably the least preferred picture-in-story formatting.
Personally, I've taken to selecting a model for the main female (or femme-male) character of my stories, posting it, and having no further pictures. I view this as similar to the 'cover art' picture, which I think most users deem acceptable, because so far my stories have been created around a central theme and then follow separate characters (which use the model character for inspiration).
The advantage of the picture is real. Pictures can be very sexy. Describing a person, especially an oft-used person or main character can be an awkward, even off-putting thing that takes up space and is still unsatisfactory.
Lastly some things when written can sound unreal - like "the stunning blonde took a 19" horsecock shaped dildo up the ass" might sound very silly in words, but if you can prove it with a picture its suddenly not an unbelievable plot point at all. That example was a little bad, and I dont necessarily recommend using pictures consistently in that way, but I think the point itself can be valid in the right context. Even if its just showing off that your bimbo body stats really can exist.
I am also a big fan of 'caption' porn, which is not so much a feature of chyoa but I think is an amazing medium for erotic picture/word team up in general with a great variety of styles.
All that aside, unless the story is specifically meant to revolve around pictures I think most stories do very well, and be designed to do well, without any accompanying pictures. You never know when this hosting or that will go down, and its much easier to preserve words, and erotic literature is just that - literature. Although, again, blurring the lines can lead to some fun.
