I was wondering how to convert my imported textures into game-objects

I can’t seem to find a clear answer to this question. I am importing custom textures; I try to make the creations into items like grass and trees but it only imports them as images. Basically, I have tried to create a custom code in c# but it seems 5.0 Unity does not support custom codes. Also, I can’t find the functions which support this action. Further I have imported some textures from my image editor and I can only get them into 2D textures. No matter what I do I can’t turn them into game-objects.

you need a mesh first, then apply the textures to the object. if it’s just the picture you want, just use a plane

GameObject,3dobject, plane…click on the scene to make it and then click and drag you texture on to it

By the way thank you tomhughes for your answer that was most helpful. Now I can make my grass. also last night I figured out that if you export the save the image as a defult and then export as a .dds onto where you save your images and then make a copy of the .dds rename it to whatever-you-want-to.OBJ and import it Unity, Unity will automatically convert it into a game object. Also I would assume the same can be done with any image editor and creator.
