If you’re like us, you’re obsessed with Pinterest. You get excited when you find pictures you love and pin them to your online bulletin boards with a sense of pride that they are yours.

With so many photos on the two-year-old social scrapbooking site — and countless more added each day — it’s common for some to only get a handful of re-pins. Meanwhile, other images pick up so much popularity that they go virtually viral, getting pinned from one board to the next.

Here are 15 of some of the most popular pictures on Pinterest — all of which have raked in more than 15,000 re-pins each.

Are any of these pictures on your boards? If not, go ahead and pin them, or leave some suggestions in the comments about your favorite pins.

Soon Twitter users will be able to use the service’s official photo-sharing and uploading features from their favorite third-party apps. The company has made photo upload functionality available to developers.

Twitter introduced its media upload API Monday to allow developers to attach images — in PNG, JPG, and unanimated GIF formats — to tweets.

The release comes ahead of Apple’s Twitter-infused iOS 5 update, and is clearly intended to get app makers and users acclimated to the new photo-sharing option.

“Photos are a fundamental way that people share context, information, jokes, and personal moments on Twitter,” Jason Costa, developer relations manager, wrote in a post on Twitter’s developer blog. “Following last week’s wider release of photos to Twitter.com users, we’re ready to share our media upload API.”

Twitter will also soon equip its own mobile apps with photo upload support, Costa says.

Twitter’s photo-sharing and uploading service, powered by Photobucket, was pushed out to all users last week. It competes directly with Twitter photo-sharing apps such as Twitgoo, Lockerz, TwitPic and yFrog.

Developers wishing to leverage the Twitter photo upload API will need to adhere to the service’s display guidelines and rate limits.

Web-based tools creator Aviary is launching an API on Wednesday that allows any website or mobile app to easily tweak or add effects to its photos.

A dating site, for instance, could use the API to autocorrect red eye, lighting and blurriness in profile photos. An ecommerce site could automatically resize and watermark product photos. And a photo-snapping mobile app could add Instagram-like filters without creating its own code. Aviary does the heavy lifting in the background.

In the past, Aviary has created APIs for its suite of web-based media editors and embeddable photo editor. Photo startup Pixable, online store creator Shopify and photo diary Momentile are a few of the companies that use the tools to give their users photo editing options.

The new Effects API, which can run without any user interaction, is somewhat of a new approach for the 4-year-old startup.

“We saw the photo filter space and decided instead of entering it (via a competing app), we should power the space. …We are expanding our offering and moving into the consumer space,” says Alex Taub, Aviary head of business development.

Just as Twilio‘s API powers group messaging apps like GroupMe, Beluga and Fast Society, Aviary aims to lurk behind the websites and apps that use photos — ultimately charging frequent users for its service after the beta period ends.
