 * @param targetList the list that should be updated when the data arrives
 * @param targetModel the model
 * @param targetOffset the offset within the list to insert the image
 * @param targetKey the key for the map in the target offset
 * @param cacheId a unique identifier to be used to store the image into storage
 * @param keep if set to true keeps the file in RAM once loaded
 * @param scale the scale of the image to put in the List or null
