<inMemory>: Constant inMemory: Constant used to save an image in memory. <Quality>: Optional integer Quality of the image saved. Value included between 1 and 100 (80 by default). Lower image quality translates into higher image compression rate and smaller file size. <Exif tag>: Optional constant (or combination of constants) Record Exif markers modified using the ImageInfoModify function: | | imgAddThumbnail | Adds a thumbnail into the image file (<File name>). If there is a thumbnail in the image file displayed in the Image control, this constant is not taken into account.

It allows the pages to be loaded faster (the images being loaded and displayed progressively). | imgSaveTag | Saves the Exif tags. If there is a thumbnail in the image file displayed in the Image control, a new thumbnail is recalculated. |
By default, the Exif tags are not saved, no operation is performed on the thumbnails.This parameter is available only if <Control name> corresponds to the name of an Image control.
