how do you guys get pictures of your items in your topics

This guide should help you; https://forums.d2jsp.org/info.php?p=41

Hey ,

I prefer to use Imgur for uploading images. Check out this guide; it is very helpful and easy to follow:

Additionally, if you have a customer perk enabled, this simplifies things greatly and allows you to post screenshots directly from your clipboard. Check this guide for more info on that:

Additional applications for uploading images if Imgur doesn't work for you:
1)https://imgbb.com/
2)https://imgpile.com/

Hope this helps.
