Welcome to PF;
I'll do my best but the answers are pretty much the same as for anyone...

How does physicist translate their scientific concept into an image or illustration to make it comprehensible and visual.
The same way any picture is made - you start with an idea of what you want to illustrate and then you draw it. If it doesn't work, you listen to the objections and draw a new picture until you get one that does work.
Does the physicist make use of computer-software to produce this illustrations?
These days - yes. Not always though ... lecturers often free-hand draw pictures in class. I think that the vast majority of educational diagrams are drawn free-hand on the spur of the moment.
The skill to draw 3D perspective pictures and educational diagrams is taught to science students at secondary level but they are exposed to such images from much earlier so they already have an idea of what sort of thing works. Drawings, in physics, are part of the language - the skills are learned like any language skill: by doing.
Who made the first very well-known illustration of gravity that causes space-time to curve around massive objects?
Probably the person who first published the rubber-sheet model. Don't know - don't really care. This is common in sciences, we tend not to put a lot of stock in the diagrams as artworks.
You could ask what is the oldest image of this model that is readily called to mind and get a different answer from different people. For me it was the movie Black Hole.
I wonder what diagrams Einstein used in the GR paper... it's available online, you could look.
Where can I find more information about the creators of animations or illustrations.
In the credits for the image or the animation.
A history of physics diagrams and imagery would make a nice thesis topic I guess ... check with a history or art department.
How does physicist explain this to illustrators so they can make the theory into an image or animation?
The same way anyone who wants something drawn does ... we make a bit of a sketch and wave our arms about a lot. The illustrator asks questions and makes sketches back and we pick the ones that are closest and suggest changes and so on until it is good enough for publication. It helps that we are taught, and encouraged, to draw from early on. There is a technical phrase for this sort of to-and-fro between two people, it's called "having a conversation". When we want someone to do some work for us we have a conversation with them until we are satisfied that they understand what is required of them.
