Hi,
I've just come across this problem on a clients site. I logged in to the admin section, selected 4 jpgs to upload to the selected folder which through up an error. Went back to look at the site and there are images missing :/ Went to edit the album and after the 4 images that work it says -
Zenphoto Error
MySQL Query ( SELECT `hitcounter` FROM `zp_images` WHERE `id` = ) Failed. Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
! I've not added images for ages, but when I left it all was well.
Any help greatly appreciated! I don't want to take the gallery down, but its a live client site!
