/**
*
* 【Module name】 TUIImageMessageCellData
* 【Function description】It is used to realize the picture bubble in the chat window, including the display of picture message sending progress.
* At the same time, this module already supports three different types of "thumbnail", "large image" and "original image", and
* has handled the business logic of displaying the corresponding image type under appropriate circumstances:
* 1. Thumbnail - By default, you see thumbnails in the chat window, which is smaller and saves traffic.
* 2. Large image - If the user clicks on the thumbnail, they see a larger image with a better resolution.
* 3. Original image - If the sender chooses to send the original image, the recipient will see the "original image" button which can click to download the
* image with the original size.

* Downloading image.
* This method integrates and calls the IM SDK, and obtains images from sever through the interface provided by the SDK.
* 1. Before downloading the file from server, it will try to read file from local when the file exists in the local.
* 2. If the file is not exist in the local, it will download from server through the api named @getImage which provided by the class of TIMImage in the IMSDK.
* - The download progress (percentage value) is updated through the callback of the IMSDK.
* - There are two parameters which is @curSize and @totalSize in the callback of IMSDK. The progress value equals to curSize * 100 / totalSize.
* - The type of items in the image message is TIMElem. You can obtain image list from the paramter named imageList provided by TIMElem, which including
* original image、large image and thumbnail and you can obtain the image from it with the @imageType.
* 3. The image obtained through the SDK interface is a binary file, which needs to be decoded first, converted to CGIamge for decoding, and then packaged as a
* UIImage before it can be used.
* 4. When finished download, the image will be storaged to the @path.
