I had it to show gallery images full size. But now the images have the ads over top of them on the right side.

Now you can click the image to open in a new window and that shows the image only but the new window opens to a set size and for bigger images you again have to maximize the window. Then scroll only if it's bigger then your screen setting and monitor.

I have a 22" widescreen set at 1280x768.

OK images open up to a set size but not wider then the top menu
