How to upload the photo into the forum and post??

You mean like this?

Yes it can. Click the IMG button while you are posting and you'll see img in brackets just after the] type in the address like Img]http/ bla bla bla .com
Or to be sure it works just type it in and not use the button:

Code:

[Img]http://www.bla.bla.bla.com[/Img]

you can also install the attachment mod. its ported over at http://www.anorscorner.com .

is it support php-nuke theme----sublack?
