Image via CrunchBaseAll the voucher pictures in our NSG database take up to 2.5GB in hard disk space, which is quite a lot for 3300 pictures only.
This is indeed a problem if we decide to move the database into a private, commercial server because buying 2.5 GB of space can be quite expensive.
Then Flickr might be able to help. By having a PRO account, users are allowed to upload unlimited number of photos and even retaining the original sizes of high resolution photos, for only 25 USD per year. Quite a bargain indeed.
Since moving more than 3000 pictures can be tiresome, I used used Flickr's API interface and grabbed an API key.
Then I found the PHP class libraries of Phlickr very useful as a layer on top of Flickr's API.
I used Phlickr to harvest information from the NSG database and included it as Title, description and Tags of the photos to be uploaded to Flickr.
Almost everything worked as a charm. However, I found that Phlickr got problems in getting the image URL, by constructing the link using the wrong id of the photo. I had to fix it by hacking the Photo.php class -> function buildImgUrl()
The database then will link to the photo on Flickr:
Now people can comment on every picture and point out whenever we misidentify the vouchers. The possibility of adding notes on top of the photo might of some use.
