it's just a warning, not an error. still should be fine. maybe your image is too large.
there are few more arguments in CreateDynamicObject, but they have default values, according to Incognito's thread. (there were no two last arguments when I made this release)

CreateDynamicObject(modelid, Float : x, Float:y, Float:z, Float:rx, Float:ry, Float:rz, worldid = -1, interiorid = -1, playerid = -1, Float : streamdistance = STREAMER_OBJECT_SD, Float:drawdistance = STREAMER_OBJECT_DD, STREAMER_TAG_AREA areaid = STREAMER_TAG_AREA -1, priority = 0);
