failed to load image"sprite1.png": png not supported 8 bit only

[doomlead]

I am using sfml 2.1, the compiler/IDE I am using is code blocks.
The subject is the error.
I recieved my code looks like this

sf::Texture texture;
texture.loadFromFile("sprite1.png"));

sprite1.png is a famtsu sprite sheet.

You have an extra closing bracket at the end, that might be the problem.

that was a typo for the forum my code doesnt actually have the extra parenthesis code blocks wouldn't have let me compile with an extra parenthesis.
everything compiles just fine its when i run it the sfml  window is blank and the codeblocks console window gives me the failed to load message

I think the error message is pretty clear... 8-bit PNG images are not supported
