You can download your Instagram photos using an application called SocialSafe. Download SocialSafe for free from http://socialsafe.net
Once you've installed SocialSafe on your PC/Mac, add your Instagram account to your SocialSafe journal by clicking on 'Add Your Instagram account', and logging in with your Instagram username.
Choose what to download to your machine with the settings cog next to your account name, then click 'Sync Account Now' to start downloading your content.
Once downloaded, you can browse and view your Instagram snaps from the 'Photos' view.
Clicking on the images will reveal all of the comments, tags and likes for each photo. Everything in SocialSafe is searchable, so you could use the search bar to find all photos with a certain tag.
