What about E-Hentai?

Im not updated with the status but it wasn't dying some months ago?

Maybe?

Well, there's Imgur. Pixiv has a feature like InkBunny where you can upload a bunch of pics as a single submission. But it's primarily Japanese, however some English artists post there.

I've never used it myself, but I believe postybirb is meant to accelerate such a process. I think it's mainly for posting to multiple sites, but I think it also allows you to upload multiple things to one website.

I didn't know of that function of it, sounds useful. Though mostly I don't want to make spam on sites filling pages with only one image variations

InkBunny.net is pretty much all about that!
Also, Patreon does it now, I think

Patreon kinda does it but this is for public release

Ah gotcha. My best bet would be InkBunny then

you dont need a zip to upload multiple images to inkbunny

You're right, but you still need to upload one by one by one if you dont use it

I don't understand why using zip files is a problem for you on IB.
You might need to ask a mod to give you the ability, but it's been easy for me to use.
Just select multiple items in a folder and use the rightclick OS menu to "send to zip", then on IB>submissions>upload multiple>select zip>resort order if needed (is automatic if you append (or prepend if different filenames) with ascending numbers), then write or paste the text & tags as usual.

Besides, IB kinda needs more good variety artists like you.

Thank you. I have the option but im looking for other alternatives too
