Wrong datatype in Images admin (Fatal error)

[fredo64]

Hi everybody ! Congratulation for your hard work !
Could someone let me know why i got a Fatal error in my "Images admin page" when i want to show more than 30 photos ?

Fatal error: in_array() [<a href='function.in-array'>function.in-array</a>]: Wrong datatype for second argument in /mnt/135/sdb/1/e/mysite/pixelpost/admin/images_edit.php on line 575

This is not a simple warning because i cannot view the next photos and cannot apply some operations on them. The page isn't complete.

i noticed that i also have trouble with ajax rating addon (division by zero line 98) and when i look at the sql base, it seems it can't create more than 30 entries :| the 29 is truncated... so i don't know if both are related or not .

any help would be appreciate
Thank's
