Functions

func LogError

func ParseUpload

func ParseUpload(req *http.Request) (int, string, error)

ParseUpload parses the upload form. Separate function for cleaner error handling and reusability. Returns the HTTP status code of the response and an error, if any.

func UnloadGM

func UnloadGM()

UnloadGM safely unloads the GraphicsMagick runtime

func UploadImageHash

func UploadImageHash(w http.ResponseWriter, req *http.Request)

UploadImageHash attempts to skip image upload, if the file has already been thumbnailed and is stored on the server. The client sends and SHA1 hash of the file it wants to upload. The server looks up, if such a file is thumbnailed. If yes, generates and sends a new image allocation token to the client.
