There is Any way or Method to find user information by using user image.
Suppose that: i have one person image by using this image, can we get user information from google+, facebook, and other social sites.
If you could use Google Image search by example programatically, you might be able to do it.
In practice, the user image on other pages might look the same but they will be compressed with different algorithms, so you can't compare them byte-wise.
All in all, it is much easier to ask the user to add the info.
You could try submitting the image to TinEye here and that does a reverse search, so it will show you all other places where that photo appears on the web.

I'm working on an application where I have a web interface for a screen on my wall, and the goal is to allow my friends to upload images to it.
Right now I have a basic web interface with a login, which authenticates a session and has a page which allows uploading an image and changing some of the parameters of the screen. The parameters are stored in a MySQL database, as well as the login details. This part I've heavily based off the approach detailed in this link:
https://phppot.com/php/secure-remember-me-for-login-using-php-session-and-cookies/
Ideally I can allow my friends to upload images to this screen in a secure way that is as simple as possible. What I am imagining is a unique URL link that can be sent to them, which takes them to a page where they can upload an image but do not have access to change any of the screen parameters and so on. This URL would allow anyone who has it to upload pictures, but I want the owner of the screen to also be able to deactivate the URL if it is no longer secure. The owner could ideally generate a number of URLs that they could share with different people, which would all upload to the same screen.
My question is firstly, is this a good approach and is there a way to do this securely (without opening access to the screen parameters and so on)? I would prefer to avoid giving these "guest" users login details, as that is one more account to remember and reduces the simplicity of uploading to the screen.
My next question would be how to do it? My current idea is to have a new database with columns for the screen ID (to allow it to work when I have multiple screens) and link URL. The screen owner would generate some kind of random string as the URL and save it to the database. The "guest" upload page would only allow uploads if the redirected URL is found in the database. Right now I'm looking at affiliate link examples to get ideas on how to implement this, but if anyone has better suggestions of what to search for or other examples it would help a lot.
I'm very new to web development so I'm not sure if I'm describing my approach clear enough or if my goal even makes sense. I'm also very uncertain of any possible security issues I may be introducing with this approach, so anyone has suggestions or possible pitfalls please let me know. I don't know how much I don't know.
You can use Tokens :
generating tokens with php
You generate an URL with the token inside then send it to your friends:
www.myULR/token
After, you create a table token with all tokens with a jointure with user's id,
and you should easily verify with PHP, if tokens exist and user is not an impostor, allow him to upload files.
After a long learning curve, I managed to successfully get the user's profile information using the Google API client libraries.
Along with a name and email address, when the user logs in to my web app, I can get their profile picture.
Trouble is, the picture is pretty big, in dimension and bytes. The url for such a picture looks something like this:
https://lh4.googleusercontent.com/-rdhxDPbmVhg/AAAAAAAAAAI/AAAAAAAAAJQ/6Dsr5psyQPs/photo.jpg
(Yes, that is me at Coral Castle).
Is there a way to get a thumbnail or icon-sized profile pic, like the kind I see next to the author in the results of a Google search? I notice these aren't a URL, but a data object, so I will probably have to do something in php to render it as an image?
An example of the image info on an author, in the results list of a Google search, looks something like this:
data:image/jpeg;base64,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
I welcome help in getting me to clarify the question, if needed.
You can adjust the size of the image by appending a ?sz=(size in pixels) parameter to the URL you got.
Example
https://lh4.googleusercontent.com/-rdhxDPbmVhg/
AAAAAAAAAAI/AAAAAAAAAJQ/6Dsr5psyQPs/photo.jpg?sz=50
Will display as
What method are you using to retrieve the user information?
The people.get method of the Google+ API called with userId=me for the authenticated User will already return a URL with a ?sz=50 parameter added in the image.url field of the response.
Just pass a parameter for size to the URL ?sz=200
It will become something like https://lh3.googleusercontent.com/--sahsjak8sjdbs5kNk/AAAAdshjgdshdgAAI/AAAAsdhsHY/knQ6LGqP1Yk/photo.jpg?sz=200
And you are good to go!
Curious if the PHP Facebook SDK allows me to change only my own profile picture and cover photo. From the reading I've done I'm thinking no, but I wasn't able to find any recent, direct articles.
Any help is appreciated.
Looks like you can't actually change it, but you can get half way!
Setting Facebook Cover Photo via API
"There´s no API support for changing user profile cover, but you can upload a photo and then redirect user to: http://www.facebook.com/profile.php?preview_cover=PHOTO_ID"
I need to create a program which allows to store photos of which people has uploaded in Facebook based on the photo description. For example, I upload/post on Facebook a picture with the description "#awesomeevent" the program should be able to store this particular image into the database. Twitter has hashtags but Facebook do not any where which i can work around this ?
I was thinking of using a FQL query but unsure how to do it.
The best (and only?) way to do this imho is to include the hashtag in the message of the photos and read it from there. I would not use FQL for that, because there is no need to use it. The Graph API offers enough possibilities/connections to read photos:

(/me/photos, /me/photos/uploaded, /me/albums, ...)
Hello I am working on an educational app just for my own learning where a user can login, upload photos, and then have them display on a website. I am a little confused on the general idea of how it should work. I know this isn't the best place for this type of question but I can't find it anywhere else.
Basically I want a user to be able to login with something like OpenID and then upload a photo ( I am using phonegap and thus they would use the Phonegap API to do this and I understand the mobile side here ) to a server and then have be hosted on the server and be able to have a user's photos displayed together.
Do I need to have each photo be submitted to a database and if so how would I store the photo info? If you have any input it would be appreciated I am a little lost. I know php for the server side I just don't know what to do.
Do I need to have each photo be submitted to a database
Only if you want to, you would have the base64 encode it or store it as a blob though. Your best bet would be to store the image somewhere on your server outside of the database and instead store its address or path in a database along with a unique ID.
how would I store the photo info?
What photo info, the exif data? Or are you talking about additional general information? (date it was uploaded, user that uploaded it, etc etc) Either way, you would make a column in the database table for each chunk of data you want to store.
For example, if you wanted to store the date each photo was uploaded and which user uploaded it, you would set up columns in such a way that a row in the database that look something like this:
(columns) id photo user date
(row) 58 uploads/img58.jpg myuser192 1338483324
as for actually getting the photos on your server, perhaps you could use an html5 friendly solution like Uploadify
