You should send the picture you want to sign to the building in the graphic area for uploading signature pictures through the attachment, and the address is here:

/tread- 1550204- 1- 1 . html

Then, right-click the picture and select Properties, and you will see an address bar.

Then copy the address bar.

Finally, you open your personal signature in your profile and enter [img]ctrl+v[#/img](# Remove, ctrl+v means you can paste the address bar between the two codes).

Then click Submit. If it is not refreshed, you can see that your picture has been added to the signature by pressing ctrl+F5.
