#1: You don't [i]need[/i] an image for your character. That said, if you simply [i]must[/i] play a character that looks like you, you could always take a picture of yourself and run some artistic effects over it in a paint program or (heaven forbid) use AI to generate something. More roleplays use art then don't, but I've yet to see someone get rejected for not having artwork of their character.

#2: This is basically not going to work for group roleplays, as the worlds are often far too detailed to just accept a character that was made in a vacuum. The only exception to that would be if you made your character for a specific fandom or board game that gets played on the guild a lot. But even in those situations, you'd fit in a lot better if you knew the RP specific lore. 1x1 RPs tend to be more purpose built for both players, with the caveat being you need to actually [i]find[/i] someone who wants to play with your character. 

I have seen people advertise their characters in the past, but as a GM myself, I would [i]never[/i] recruit a player this way. 

If you're determined to do that though, I think you'd have better luck putting your character in a 1x1 interest check than joining a group game.
