I'm having this same issue with images in Description and trying to render the content using wiki. I tried to replace the size of images without success. I'm trying this
${wiki%{'${escape:<span>JQLIssues[j].</span>Description}'.replace(new RegExp('width=\d+,height=\d+!','g'),'width=200,height=200!')}}
I noticed that the image tag is coming like this:
!image-20200417-132307.png|width=1801,height=561!
I tried to remove the whole image and try to change the size without success.
Any thoughts?
