Hello.
I have 17000+ pictures and 4.1Gb database.
I decided to move pictures to filesystem.
It is not possible.
I did some research and found this code:
if (this.StoreInDb != value)
{
//save the new setting value
_settingService.SetSetting("Media.Images.StoreInDB", value);
//update all picture objects
var pictures = this.GetPictures(0, int.MaxValue);
thats really critical bug, because it will be never possible to move pictures to file system.
other bugs: when you open product details page it download picturebinary from database allways before checking if thumb exists...
