Mohammadreza, I am a great admirer of your work, but have only just recently discovered some of your Max / Corona tools. Easy HDRI and Color harmony are fabulous tools, but I have a couple questions about Easy HDRI.
1. I have no problem running the script from 'Script > Run Script' but it does not appear in 'Customize User Interface > Toolbars > Category (?)' - or at least I do not know the category it is listed under.
2. 'Load HDRI' function launches Windows Explorer, but only shows supported file formats, i.e. not JPG, PNG, TIF, etc. I understand why it is implemented in this way, but if the folder contains preview thumbnails for an associated HDR / EXR, the thumbnails are not visible, so a selection must be made based on file name alone.
