Dear Sabir Mughal , you can't upload an image from you computer because we have disabled this option for regular members, if you want to post any image try second option i.e upload it first at some free image hosting website like loadpictures.net. I am repeating step by step instructions again here.
Please follow these steps to post images on this forum.

Internet Explorer: Open the Image > Right Click > Properties > A window/dialouge box will appear >

Insert Image option
Chrome : Open the Image > Right Click >

Direct link copy and paste it into
