Windows Vista Refresh Page Full Quality

I am using a Windows Vista Home Premium (32-bit) PC with IE7. I use AOL 9.0 Vista Ready. On my old XP computer, I had the option to right-click an image, select refresh page full quality, and it would improve the look of my image. On my new Vista PC, I do not have that option on either AOL or IE7. I tried the tip in the XP forum about going to Tools, Internet Options, Advanced, and selecting Enable auto resizing under the Multimedia section, but it was already selected. Is there a way to fix this problem?
