May be wise to just re-post the images here, as opposed to redirecting viewers to a different, and possibly unfamiliar forum. Where are the images hosted? You can use the image button or manual image tags
I'd say since these images originated from 4chan all that info was in the actual image thread, accompanying the image, image working as a "look here about what I'm writing on", to later be spread threadless.
I`m not sure if it`s on my end, but images don`t load ? Try imgur, copy path for "direct link" to image then put it in the add image url. Then the images are inserted for in the body of the forum :)
The images are too small to make any comment about really. Prepare some larger images and use the 'insert image' icon when posting, so each image is expandable here, not on another tab.
I'm not a big fan of the mouse-hover appearance; the image is almost totally obscured when the mouse is over an image. It's more common for the normal image to appear when the mouse is over it, and for the default image to be different.
