Currently the preview box in the script info maker works correctly with base64 images, such as this one

<img src="data:image/gif;base64,R0lGODlhDwAPAKECAAAAzMzM/////
wAAACwAAAAADwAPAAACIISPeQHsrZ5ModrLlN48CXF8m2iQ3YmmKqVlRtW4ML
wWACH+H09wdGltaXplZCBieSBVbGVhZCBTbWFydFNhdmVyIQAAOw=="/>

However, when the user submits the script description containing base64 images the website looses the source, returning simply an empty <img> element.

This image method is not appropriate for big images, but for small images it works really well and prevents the need for users to host their own images somehwere where the connection might not be https (causing the browser to show an insecure connection warning when visiting OpenUserJS; this one is a perfect example of that Anti-Adblock Killer | Reek) or risking the image to die, or its link to change for some reason.

Re: @ParticleCore:

returning simply an empty <img> element.

That is intended behavior. RFEs of this nature should not be done in this discussion forum and ideally they should be done through the Development link as referenced in the footer. This forum is currently for UserScripts not the site itself. Thanks.
