If you are looking for a way to publish your preferred photos that you have on your Mac or PC straight to Instagram, without having to first transfer or copy them to your iOS or Android smartphone, here is a free tool that does exactly this.

Gramblr is available for both Mac and PC and it allows you to upload any picture you have sitting on your hard disk to your Instagram account. You can add your comment and hashtags, but you cannot take advantage of the filters you normally available in Instagram.

Free.
