Since the upload code of the applet cannot check 2M, the processing method is as follows:
1. Make sure that the local image added to the applet code package does not exceed 2M, in order to refer to the local image;
2. If there are many icons, you can consider using iconfont font icons. Since the applet does not support http and requests cross-domain, go to this platform https://transfonter.org/ , convert the font file into base64 format, and then link
3. Put the picture directly on the server, and then use the absolute path to reference
