For less than $5 you can get the Etsy sellers app for your iPhone/iPad.
It works great!
I use it to make my listings from my phone. It is what I use to get the photos into the listing and all the basics in the listing becaus the app does not do when was it made and styles and such...then once I have that part done I list it.
Then I go to the web broswer, and go back into the listing to add the when was it made, by who, who is it for, occasion, style etc.
The app is the only way to get pics loaded.
