Just played with some of the core files to get the admin working. Under wpsc-admin find display-options-settings.page.php and navigate to line 127. There is a variable for $link that holds the links in the admin section. Simply add target=’_parent’ right before ‘$class’ and you’re set.
Not sure about the other issues. Just now trying this cart out.
It may not have worked b/c I did this for contributors, not authors. I think authors could already upload… may be wrong though.
Disable any plugins you may have installed recently and see if one of them is interfering with the media icons. Also, you can check the source code to see if it’s even displaying. My container div is called ‘media-buttons’.
Contributor won’t work by default, but I just posted a hack to that: http://ww.wp.xz.cn/support/topic/270389?replies=1
