The most advanced Internet photo searching, browsing app. Read through the description for the details!

picTrove supports these photo services:
⇨ Google Images
⇨ Bing Images
⇨ Flickr
⇨ Picasa
⇨ Photobucket
⇨ Facebook.com
⇨ Tumblr.com
⇨ Wordpress.com
⇨ Blogger (blogspot.com)

⇨ Cross reference - When you find a picture you like, you can find more of the same very easily:
Google Images: Search within the same website, or even see all pictures from the particular website or the same *web page* !
Bing: Search within the same website, or see all images from the website of the photo.
Flickr: Browse user’s photos and browse the user’s favourites
Picasa: Browse user’s photos and browse all photos from the photo’s album

⇨ Saved Searches - picTrove saves any searches you do, and shows you your most used searches on top. No more hassle remembering what you typed to get what results. Saved searches are available across all services - you can compare results from one service with another, it’ll even tell you which services you’ve searched in.

⇨ Image preloading - While you’re browsing through images, picTrove is downloading further images in the background so you don’t have to wait for images to download.

⇨ Downloading progress - When you do manage to beat the Image preloading, and are waiting to see a downloading image, you’ll see a neat Pi chart representation of downloading progress, along with a super-enlarged thumbnail to let you skip ahead if you so wish.

⇨ Edit photos with Aviary to enhance searched photos. Edited photos are stored within picTrove in the Downloaded Photos section.

⇨ Share and publish photos with supported apps. You can open photos you find in iPhoto, Dropbox, Box.net app, Halftone, Evernote, Autodesk Sketchbook and more. Share photos with Twitter and Facebook (iOS6 only).

⇨ picTrove tries to find the highest quality images for your searches. A crisp pixel-perfect image is custom-created directly on your device to support your device screen exactly. Tested with very large photos and endlessly tweaked to give you perfectly sized images, fast! No more jagged photos, or stuttering while scrolling through over-large images.
