Well, one solution would be to get preview-latex to shrink images automatically to a maximum size. However, it your preview indeed is quite taller than wide, this renders it unreadable. Also, having larger equation blocks shrink to fit some small widown height will make them not line up with other equations. By the way: there are also large performance problems with mouse-highlighting and cursor blinking on images: while they are most visible with larger-than-window images, it is also apparent that while the border line of the box cursor is blinking, the area of even small images is intermittently in background color, so it would appear that it is overdrawn in white and then replaced again. On a local display, this might be tolerable for small images. Over a low-bandwidth connection and/or with large images, this is a problem. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
