This is a test of the file upload with a PNG based zif format tile.  At 895 meg this file will stress the upload capacity of the site. I hope it will success the files faster when zooming in and out. the delays when changing between zoom levels is most distressing.

It is taking a long time to upload but it IS uploading at the max internet limited rate.  7-8 MBPS.

The file format seems a bit better in terms of focusing on zooming between layers but the delay is still verry apparent.
