    Why is it so hard to find out how much it costs?

    Now that I've purchased JSN ImageShow, I'm disappointed to find that the quality of the thumbnails it generates for the "Theme Grid" are so blurry.

    Also - would like to see option for image auto-advance in the THEME GRID lightbox.

    Hi edgibson,

    Thank you for your comment. Let me answer your question:
    - Currently, ThemeGrid doesn't allow you to choose image sources to display thumbnails (By default, it displays thumbnails at 150 pixel). That is, thumbnails are blurry. We will improve it in the next version.
    - In this version, to make thumbnails sharper, you should use the source Flickr. With it, you can choose thumbnail sizes.

    Could you explain the idea " option for image auto-advance in the THEME GRID lightbox" more clear? I don't get it.

    I would like to know if it's possible in the ThemeGrid to have "smart" thumbnails, i.e. that are not blurry and that are made according to thumbnail pixel size. The problem with Imageshow is that you can't put thumbnails because it's blurry, so you have to put the original source, and then the whole page takes AGES to load (if you have a photo gallery website, which is my case)

    Example : My thumbnail is set to 220x220 because I want it to. Because I want my visitors to load the website page quickly, I enable the thumbnail option. But the thumbnails are incredibly blurry, and the whole idea of "thumbnail - save loading time" becomes useless and frustrating...

    Is there a way to fix this ? Does the PRO 4.8.3 version fix this ?

    If yes, I'm buying it.
