So use [ ] brackets instead of { } , but if you do the following, you do not have to convert them over. I would also recommend people doing this in general tbh.

• Right click on the image and copy image address.
• Type {img=YYYpx} {/img} and paste link in between. (Check your link to make sure it is the correct thing!)
  Example: {img=YYYpx} https://harem-battle.club/attachment...134426&thumb=1 {/img}
• Remove the "&thumb=1" part.
• Set an image size by replacing YYY with a size in pixels. In general, a small image should be <100px, a medium <300, and a large <600. Do not make your images too massive. Remove the "=YYYpx" part to use the original image size (Warning: this is usually really big).
  Example: {img=600px} https://harem-battle.club/attachment...8&d=1546134426 {/img}
