[google-appengine] store images in datastore using php
Hello, Is there some example code in PHP which will enable me to store / retrieve images (jpg, png files) to / from the google datastore ? I found example code for python(link: https://developers.google.com/appengine/articles/python/serving_dynamic_images) and java (link: https://developers.google.com/appengine/articles/java/serving_dynamic_images) but not for PHP. If someone has a working PHP code for storing / retrieving images to / from datastore , it would be great if you could share the code. Thanks and Regards, Rohith -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] store images in datastore using php
Well PHP runtime doesnt actully have direct access to the DataStore right now :) Have to proxy it though say the Cloud Datastore. https://developers.google.com/datastore/ Which is then just an exercise in accessing a remote API. https://gae-php-tips.appspot.com/2013/12/23/getting-started-with-the-cloud-datastore-on-php-app-engine/ But frankly storing images in the datastore, is probably not the best practice. Using Google Cloud Storage would be better. https://developers.google.com/appengine/docs/php/googlestorage/ On 16 August 2014 10:26, Rohith D Vallam wrote: > Hello, > > Is there some example code in PHP which will enable me to store / > retrieve images (jpg, png files) to / from the google datastore ?

Re: [google-appengine] store images in datastore using php
thanks a lot for your reply. Actually i am a novice to GAE. I could not understand your reply very clearly. Is there a difference between "DataStore" and "Cloud DataStore " ? my requirement is that i need to retrieve an image ( for eg: profile photo of the logged in user) quickly at run-time. I learnt that this was possible by storing the data in Datastore. In the Datastore, I am able to store strings (for eg: username, address, etc) using php remote api of the php app engine ( basically using the second link that you have sent ). Basically I have created an entity in the datastore and the entity has fields called "name", "address" ,etc which are of string datatype. I was wondering if I could store the image of a user as well in the datastore by creating another field with suitable datatype for holding images and access the images in the datastore with PHP remote APIs ? Is such a thing possible ? It seems to be possible with python and java (but I have not actually tried it out ) but with php i could not find any solution. any help would be greatly appreciated. Thanks a lot again !

Re: [google-appengine] store images in datastore using php
As Vinny and others have said... use Google Cloud Storage and dynamic image serving. BUT please also star this issue: https://code.google.com/p/googleappengine/issues/detail?id=9979 To make a long story short... when the dynamic image serving service resizes a jpeg image it effectively uses a quality parameter of 100. So, if you're like me and save a single large-ish image and rely on dynamic image serving to deliver thumbnails and intermediate sizes... you can end up with 2x-3x larger images than necessary. For example, I save images in GCS at 1440x1080. An example image served dynamically with GAE image serving at 320x240 is 34k in size. Taking that same 1440x1080 example image and creating a 320x240 jpeg with quality=85 results in an 18k image and at quality=65 results in an 11k image. Visually, the quality is still decent even at q=65. What I'd like to see is the dynamic image serving default to quality=85... that is a pretty standard setting. Ideally (as the issue mentions) an additional quality parameter could be tacked onto the url (but that is gravy). A simple switch to a default of 85 would save a lot of bandwidth on image heavy apps.
