Dear Sir,
Thank you. It works. However, when I click "Rebuild Thunmbnil" and set up the Thumbnail size in pixd was 150. The result was, all Thumbnils looked ugly. I deleted all thumbnils and re-used 'auto-thumbnail' option. It works fine.
I guess, there may be a bug in "Rebuild Thimbnil" that you gave me, correct? If so, how do I fix it?
By the way, what is the Thumbnial quality 0 t o100? I set up to zero. I am using 4images 1.7.7.
Thank you for help!
