Wait...I also now remember why I didn't rename the CSS. I was not sure if the script would call from he shadowbox.css if it was renamed to shadowbox1.css. I had tried it before but both my shadowbox.css and my shadowbox1.css were being refrenced to in my same header page. I didn't know how to make the script choose the right CSS.
So even if you only refrence one css like shadowbox1.css will the script recognize it? Test it out and let me know. I was super tired when I did it so I didn't test that one.
As for deleting the graphic...well if your css is in a different folder then it may not even call the graphic because the grahic is not in the same folder. So maybe you won't even need to edit the css. If you rename the css and still keep it in the same folder with the rest of the shadowbox files...for sure you will need to edit the css because remember that you still want the close X on some of your shadowbox pages.
Well I created a duplicate css file and just deleted the close graphic filename. The X was indeed gone, but the action was still there. (But since it's invisible, no one would know it was there. Out of site out of mind etc..)
So it works apparently. However, not for what I need exactly, but good to know aye?
oldish thread, but you can set displayNav to false in the options object that is passed as a parameter when calling Shadowbox.open. Set a specific open to a specific link and you can hide the x on specific links.
