Cannot get overview image from gbrowse_img

[paaatrick]

I'm trying to generate an overview-style image with gbrowse_img, but I cannot seem to work as I expected.

The documentation says "If you use multiple name options, then this script will generate an overview image showing the position of each landmark." However, when I construct a URL like this:

[gbrowse_img url]?name=SYMBOL1&name=SYMBOL2

The resulting image is just the region for SYMBOL1.

The documentation also says "Setting overview=1 will force the overview to be shown in all cases". So, I also tried:

[gbrowse_img url]?name=SYMBOL1&overview=1

Again, it just shows the detail panel for SYMBOL1.
