I don't have the newest GPU, not the most VRAM. So I go for 915x572 currently. I didn't had issues with the images size here, so far.

That resolution shouldn't be any problem

On which comment/post I've to click on re-thread? the first, none?

Great job! You can simply drop the link to your container in the megathread, and add some category tags. Something like this:

#coffee #mountains #sunrise #aigraphics #aiimages
https://inleo.io/threads/view/ben.haase/re-leothreads-wcu3zr7m

(to re-thread a thread, you simply paste the url of the thread you want to re-thread)

So it's not particular necessary for a #container post?

Not sure I understand the question. Any thread on any level can be re-threaded

If you want to help add to the megacontainer, simply paste the link to your sunset/coffee-container thread into the ai graphics megacontainer

– completely optional of course

I think now I got the idea. 😂 😅
