CSS wont display div background picture

[mikebd]

It displays perfectly on my computer and it used to display normally online until I tried to replace that background picture, I don't know what happened, I've tried reverting back to old one now that one doesn't work either. As I can see all other styles apply so do the pictures (which are all in the same folder - they load through css). So the CSS is okay, formatting is applied to text, divs, buttons and everything. The path should also be okay because background image is loading normally through the same code and is in the same folder.This one loads perfectly :\[code\]html { background: url(images/background.png) repeat;}\[/code\]This one wont load no matter what :\[code\]#container { width: 588px; height: 617px; background-image:url(images/maintext60.png); margin: auto; }\[/code\]Picture exists in that path I've checked a million times. I can access it through direct link in a browser. I've also tried \[code\]('images/maintext60.png');(/images/maintext60.png);(../images/maintext60.png);\[/code\]And all other things I've found online. What happened? I didn't change anything except the picture name and now the first one which worked - doesn't! The Internet hates me.
