This is the crude code a colleague has produced to suit our needs for a image repository and proxy as an alternate to one we already had based on picasa web albums, whichs api fails more and more everyday.

Changes are mainly in:

• able to create any size based on params w,h not just fixed sizes
• changes to pagination so we can see a complete XML files of the available images
• added a "count" option to controller so we can determine total amount of images on search
• added a feature to return the position "x" of a search instead of only by id
• watermark for images on creation
• changes to importer to add/update images
• additional cache for queries
• hash for user to use on non-logged URL queries

Thank you for your PR and the work on phtagr. I appreciate your time and your will a lot.

Unfortunately, it contains too many changes at once. Some changes break the database migration path (api column), some code parts are not clean and some comments are not in English.

If you like to apply your work and improvements I advice you to create smaller PRs for better review. Further, on basic changes (like database, query caches, arbitrary preview sizes) I would like to discuss these feature requests (and motivation) on the mailing list.

Do not hesitate to ask any question e.g. how to create a database migration. I will do my best for an kind of support.
