Pics without border

Hello everyone. I'll be in Germany this weekend and will add my full collection to the site. I know there are some coins that I have that are not yet on the site. So I plan on adding these to the site and also though of adding better pictures of some coins on this site such as for example on this one https://en.numista.com/catalogue/pieces10874.html as I posess one that is in uncirculated condition and the one shown is not even in VF condition.
So, sorry for the long text but my question is how do you get the picture of the coins to not have any borders? (I hope you understand what I mean). Can you do that with Paint or with Gimp?
