I tried a few apps, they charge to remove the background which is white with some shadow, is there an app that will check the photo as is and let me know its good?
If you can't find white sheet or a white wall in your home. Go to any post office who does passports and use the backdrop which they have when they would take the photo for you.
Or go to anyone's home with a white wall.
I just did a photo in my car for my little one. Took a white diaper sheet and draped it across the seat and then sat the little one up and took 20 photos. Found the best one and bam was done.
Too much of a hassle to download apps. So I just use one of these free websites to upload pic and save as a 4×6 and print out and then cut the 2×2 squares.

Though I find Walgreens prints to lately be a tad blurry. So either try cvs or some other place for cheap. Or if you can wait a few days ship it free from Amazon photos for a few cents.
