@Syed20b , its easy to upload a picture to Pakwheels , go to post reply, a new page will open in the upper tool bar you will see an icon of PAPER CLIP that says attachments , click on it and another window will pop up in that window just choose your image which you want to upload , when you are done just hit upload and Voilà its done ...... so simple 
Looking forward for the pictures of that 20B rotary
