Change Upload Button to image, urgent

Your best bet, without risking breaking functionality, is going to be using CSS to style it to look like however you want, including possibly a background image for it.

do you mind giving me some more details?
Like css code for which function? It is already part of the existing css code?
Can you provide me with a sample code

Thank you!!

#uploadimage_btn {
    color: red;
}

This is all going to be standard CSS and nothing specific to WordPress or our plugin itself. We don’t have any custom CSS tied to the output itself since it needs to inherit as much from any user’s theme as possible.
