我是一个新手，我尝试使用ESP32开发板与ILI9341使用Web_jpg显示图片，我发现以jpg为结尾的链接可以正常显示，但是以没有jpg结尾的图片可以下载到SPIFFS中，占有正常的内存大小，但是不可以显示，代码在运行时似乎直接跳过了。 ` Listing SPIFFS files:

Translated using Google translate: " I'm a newbie, I try to use ESP32 development board with ILI9341 to display pictures using Web_jpg, I found that links ending with jpg can be displayed normally, but pictures ending without jpg can be downloaded to SPIFFS, occupying normal memory size, but No display, the code seems to be skipped directly at runtime.

I have run the SPIFFS_Web_Jpg example and the picture is drawn. This is the output on the Serial Monitor window:

I assume this has been resolved.
