The Mashable Photo Challenge this week is all about firsts.  After more than a year of anticipation, Instagram is finally available for Android. Within the first 24 hours, over one million Android users have downloaded the photo sharing app. That’s a lot of people finally getting to post their first Instagram photos.  In the spirit of these new Instagram for Android users, we want you to show us your firsts.  However, by “firsts” we don’t want to limit you to your first uploaded photo — we want you to interpret this challenge for yourself. It could be the first photo you uploaded to Instagram or any photo sharing service, but it could also be the a photo of your first puppy, a photo of the first thing you see in the morning, or a photo that simply represents a new beginning.  My photo for the week is one of the first photos I took after moving to New York City (taken with a Blackberry Bold 9930 and edited with Instagram for iPod Touch).  Send us a photo that represents a first to you. Just make sure to include a short description of your photo in your submission. You can also send the photo in a tweet to @MashableHQ, with the hashtag #MashPics.  Also, check out the photos from last week’s challenge:  Each week we’ll select some of our favorite photos and feature them on  as well as on our  . With this challenge, we want to emphasize that all skill levels and types of camera are equally valid. We strongly believe that interesting images can be captured with anything from DSLR to a flip phone.  We will choose images based on composition, originality and overall appeal.  Submit your photo by Wednesday, April 11 at 12:00 p.m. EST. We’ll feature some of our favorite photos on Mashable, as well as on our Facebook page. We can’t wait to see what you come up with!
It's Wednesday, and the Mashable Photo Challenge is back.  This week we are asking you to submit a photo of a "first."
