As a new member, you won't be able to post pictures on the forum yet, regardless of your activity level. It's just one of the rules here. In the meantime, you can try hosting your image on an external site and linking to it in your post. This can be a good workaround if you need to include an image in your post.
Additionally, it may be helpful to check the forum's guidelines and rules for new members:
Newbies - Read before postingYes I am following your advice very carefully sir. I have read the rules for newbies, and I understand that to become a Jr member I need to have 30 active days on the forum and make 50 useful posts
If I want to post a picture on another forum, the amount of time it takes to upload will depend on the policies of that forum and the speed of its servers
