Those having the issue uploading pictures will be using the Mod Rose or Mod Blue themes, so if they select another theme, i.e anything but Mod Rose or Mod Blue, which leaves 6 to choose from, they should find that images attach ok.

so how does one do that?

User Control Panel (User CP) >> My Profile >> Edit Options >> Other Options >> Board Style

how do i delete a post  ?

just report your post and an admin will delete it

Is this growth ?

Can not see it myself

Remember that images have to be smaller than 500KB.
I just made a script to resize them to an acceptable size for this and other forums. Try using this

and upload on this forum the output of my tool.

P.s. the tool is "experimental" (meaning that I developed it in 30 minutes). It may break or it may not work properly.
