Oh most of us that change it so often make the شبیہیں ourselves.
If آپ ever find an image آپ want to be an شبیہ I could always make it for you. XD Ive made probably near a thousand یا so شبیہیں سے طرف کی now. I really enjoy making them
But essentially آپ تلاش up whatever آپ want an شبیہ of, آپ find an image that آپ think would make a good icon, take it to some kind of editting software (or paint if آپ dont plan to do much to it), and at the very least, crop the image to be the size آپ need it to be (square)
آپ can get مزید creative with it the مزید your practice too
I usually used
link to ترمیم and crop and all cause its like Photoshop but online free and has no downloads. Not as good as Photoshop but definitely plenty enough.
