potential bug in (image) upload function

1. search WISE coadd images, 4 bands, 500" size at any target, I used 56
2. upload the attached image from "Images" panel
3. click the list icon to open the list dialog, you see the uploaded image is selected. 
4. delete the uploaded image, 
5. upload the same image again from "Upload" menu
6. click the list icon again to open the list dialog, the uploaded image is not selected, and can not be selected either. Close the dialog will make the image go away. 
7. And there is no way to bring the uploaded image back to display

I tried other images with less extensions without above issues. I suspect the image itself may be special to cause the problem.
