Lightbox or Colorbox. I would say colorbox, its successor to thickbox, which i always liked, its smarter and just feels better.

You installed your CKEditor and IMCE but there is only image dialogue on your node edit screen and you want to add plain file link.

Fastest way i found to make small changes on your site is to use FTP program like FileZilla. Then you just go to file you want to edit and click view/edit. File is downloaded locally and opened in your default (or the one you set in FileZilla) editor.

Having problem with Flash when using lightbox for overlay? Just add transparency to those flash embed codes and they will be in the dark.

<param name="wmode" value="transparent" />
<EMBED src="swf.swf" quality=best bgcolor=#FFFFFF wmode="transparent" WIDTH="550" ...

There is a "31 stylesheet limit in IE 6 & 7" so sometimes your page will break in this browsers. You will go crayze, asking yourself whats going and, checking CSS and tags.

so put it in function
