Well, in the previous thread, I gave you some code that shows how to dynamically load emoji from file based on the filename. You can use that same method to load whatever images you want dynamically, or just define a new quad as I also told you how to do if you don't need dynamic loading. 

Your example code is already using a lot of custom classes, which I asked you for more details on before and did not receive (I don't know what UTM_StaticData is), so I'm not sure how much I can help beyond what I've already done! This code is unreadable to me without additional context, I can't make sense of "method_15", "Boolean_0"... Not only are they not in the context of the script you sent, I can't infer what they are meant to represent based on those names. 

Yeah I'm sorry, but I don't think I can say that much more on this custom system of yours... The compiler-generated code is impossible for me to figure out, and I can only really give support on my own code... I fully support writing your own extensions, but apart from how to write the implementation, I can't help further than that!

So... if you can load custom emoji as quads, you can load any image as a quad! If you go through the emoji code, what you can do is take the part that looks for an emoji based on file name, and adapt it to load whatever image in a Resources folder as a quad. When you grab the image as a Texture2D, you can even use the dimensions to determine the size of the quad.

And I'd still recommend just using a standard image/spriterenderer for this if your banner is on a different row, anyway! That way, you can just skip applying it to a quad, and put it right on an image renderer.
