Thanks a lot Chuck S.
Its working now.
Do you mind if i ask you one more thing ?
How can i increase the thumb size for the "Linked Thumbnail" under the picture.
When i use that code in forum (vbulletin), the current thumb size is very small. Which size do i have to change ?
My websites : DW Gallery - Free Image Hosting - Main Index
Its still in testing mode...
And another problem is, as you can also see from my index page, i couldnt solve the problem with the showing non-English characters. I've changed the language to charset=iso-8859-9 but still can not make it show right characters.
