Okay, I’ve managed to go into the ‘code’ page to manually type in < img src= “https://www.blablabla.com/image.jpg” > and it worked.
BUT, if I tried to insert the picture in the ‘visual’ mode and selected it to align in the middle, the source code will just show this:
<img align=”middle” />
If I didn’t select any alignment or type in the image description (just enter the img url only), I get a blank code page.
