Please tell me i'm not the only one completely confused by this program xD

Is there perhaps a simpler option?
I found no tutorial on how to do this process utilizing ImageMagick (Im so bad at this )

1. Upload your pictures on an external picture upload site, such as Imgur, Giphy or others.
2. When those are uploaded, the above sites provide you with a Image link (Usually ending in a .png or .gif or whatever)
3. copy/paste those image links onto your forum post, with "img""/img" around it.
4. Profit

Hey guys, Daniel here.

I wanted to know, is there any way I can effectively ensure that I will be getting paid through any sorta contract? Do you artists commonly provide some sorta legal document that the employer should sign in order to confirm payment?
I've never had any issue with employers, but have heard of tragedies occur between employers and their employees before, and as such, I want to know of any potnetial assurance methods that will confirm that payments will happen, and promises will be complied. This especially is important to me when it comes to the artist gaining a % of the final product. How does one confirm that they are actually getting, say, 20% of the earnings, and not being victim to fraudulent acts of miss payment.

Thanks in advance.
