It's still in beta! To use the new advanced features, you need a modern computer with a relatively fast processor and Firefox 3.5 or later. There are still some rough edges and your feedback is very welcome.

It's handy for viewing large deviations.This is part of the
deviantEXPERIENCE extension series.

How to use it?Click the Panorama View link to the left of the deviation. Grab (click and drag) the deviation to move it around. Use your mouse wheel to zoom in and out the deviation; or if you don't have one use the zoom icons or the zoom slider at the bottom right corner.

Important stuff!It's
HIGHLY recommended that you use this extension with Firefox 3.5 or later because it has a fast JavaScript implementation that's very beneficial to the image processing tools included. The new features are
resource intensive processing-wise and will perform
slow on older/slower computers. The original functionality (panning and zoom) is still very fast as it was, on even on older machines.

I installed it, I'm using the newest version of Firefox, everything else is up-to-date as well.
Do you have an idea what could be wrong?
Because really would love to use this.
I actually used your blue elephant for testing while developing this extension!
