@Pierre Aubameyang, have you considered cutting these yourself? In most cases, your images are of a very good quality and with remove.bg and photopea.com, it wouldn't take you too long to do them yourself tbh, a couple of minutes each. You'd avoid having to wait for us to come round to them…

@mons, Already tried but nothing is left, so I gave up :/

What do you mean by 'nothing is left'? With the technique demonstrated in the below video, it takes you a really short amount of time to do an excellent cut. Perhaps you hadn't seen it so you can tell how best to use both free tools effectively and quickly.

This source took me 2 minutes and 17 seconds between downloading the image and uploading the final cut, and it only took that long because remove.bg for once didn't cut it perfectly so I had to cut off a bit manually which took me over the 2 minute mark. I have never had any graphics design training and learnt all this here, so I'm sure anybody can do it too 🙂
