Adding Images

I am trying to add pictures to a weblog, but i get this message constantly:

Error in application 'antville':

Error creating image: Bad parameters or setup problem. detected at line 11 of function 'saveImg' in file: 'image/objectFunctions.js' called at line 45 of function 'evalImg' in file: 'imagemgr/objectFunctions.js' called at line 15 of function 'create_action' in file: 'imagemgr/create.hac'

What can i do ?
