Problems with Category and Document Thumbnails

Hello, I have recently purchased eDocman. I have uploaded some thumbnail images for both a Category and a few Documents. I am unable to change the thumbnail sizes in the Joomla back-end Component at the Components -> eDocument -> Configuration -> Category Thumb Height/Width or Document Thumb Height/Width. Also, the thumbnail images do not "pop up" to display the full-size image, as they do on your Demo on the Joomla Extensions site.

Is there a way to change these sizes using "Configuration", and also enable the "pop-up" feature?

Also, I note that they are uploaded to a much lower resolution than the original - which I can see when expanding the size using the custom.css file. Is there a way to improve the resolution?

OK, I have answered the questions about the Configuration and Thumbnail file display sizes and resolutions! You have to set the settings in "Configuration" first, then upload the file, and it will set it to the display settings and image resolution AFTER you upload it.

Is there a way to get the image pop-up as in the demo?

Hi John,
Can you send me the the link to image popup in the demo site?
Thanks
