Every time an Image is uploaded using I-Load, the component can store several files (See How many and which files are saved by I-Load).

I-Load uses its naming system in order to avoid collisions and to detect the various files associated to a single image.

The file names generated by I-Load always have the following structure:

[IMAGEID]_[SUBFILEID].[EXT]

Where:

• [IMAGEID] is the ID of the image (see the Id property of the WebImage class.)
  All files associated to a single image have the same [IMAGEID] as a prefix.
• [SUBFILEID] is the ID that allows the various files associated to an image to be distinguished.
  For customized thumbnails, the [SUBFILEID] coincides with the InternalCode property of the WebImageResizeDefinition class.
  There are also some IDs that I-Load uses by default:
  
  • "__Source" identifies the original images uploaded by the user
  • "__Selected" identifies the image files selected by the user
  • "__Icon" identifies the icons visualized by I-Load
  • "__Index" identifies the XML index files of the images
• [EXT] is the file extension (jpg, gif, png, xml, etc...)

Example
These are the file names that I-Load could generate for a hypothetical image having ID "123".

• "123___Source.bmp"   (the original image uploaded by the user)
• "123___Selected.jpg"   (the image selected by the user)
• "123___Icon.jpg"   (the icon visualized by I-Load)
• "123___Index.xml"   (the XML index of the image)
• "123_MyThumbnail1.jpg"   (thumbnail "MyThumbnail1")
• "123_MyThumbnail2.jpg"   (thumbnail "MyThumbnail2")
