I am not sure about how to deliver work

[comicstylish]

I am making emotes and I deliver each emote in 4 sizes. So I put them in a file seperately and send it to client as a zip file, also I know fiverr doesnt watermark it so I am afraid if someone takes the zip file without watermark and cancel the order. I am new to these things and couldnt find an answer.

Should I upload all of them as a png to deliver section or maybe I just send one image includes all the emote previews and after the order is completed then send it as a zip file?

Am I making it too complicated? Please help me I dont know what to do…
