I assume now you already know how because of some suggestions from the seniors here, and now you can immediately put it into practice so that the knowledge you get today is really useful for you.

There are several image hosting sites that you can try to post images on in forums, including:

• https://postimages.org/ - You can also use the telegram bot to do this ^{[@Postimages_bot]}
• https://imgur.com/
• https://imgbb.com/
• https://zizihub.com/

I tend to use imgur and imgBB, but recently imgBB has had a bit of trouble hosting image. So instead you can use the other three hosting sites above. But I think there are some other hosting sites that you can use, but above are some of the popular ones here.
