Hi I have tried to transfer my existing images to Adobe but every time it asks me to sign up for an account and I already have an account so do not want to add to my bills, please can you assist me, thank you so much
There would be 2 options, one to sign up for a new Adobe account and other to sign in to an already existing Adobe account.
You can also open stock.adobe.com in one of the tabs of the browser and sign in to it with your existing Adobe ID and then try the transfer process. In that case, it will pick up your already existing Adobe ID.
Let me know if that helped.
