You can send texts from your pc via email. To do this for Cincinnati bell customers, use the following general rule:
Send an email to 'cell-phone-number at gocbw.com' (obviously use an @ symbol instead of the word, however the site would not allow me to post an email address)
Replace the words 'cell-phone-number' with the actual phone number of the Cincinnati Bell customer that you wish to text.
For example, if your friend's number is 123-456-7890 then you would send an email to 1234567890( at) gocbw.com
There are sites on the internet that will allow you to send sms to anyone on any network, though I would think that some of them may not be safe, especially if you are sending private messages or business type ones. In which case I assume the email method above would be safer.
I am not sure if this will also work for sending photos, but it is certainly worth trying.
