100% totally agree. You should also use proper metadata for greater discoverability of your images and for Google to understand what they represent.My advice is to upload only good quality images with proper titles and descriptions. That gives better results than posting everywhere.
today, the submision of pictures is more for visibility rather than optimization. unique and imprtant picture can create brand mention, get trafic through image searche nd get some referral trafic, but that is about all.Hey
How beneficial and good do you guys think image submssion sites are?
