`randImg` returns an invalid URL string

[maper89]

Is this a regression?

Yes

Description

After a recent update, the randImg function returns an incorrect URL. The issue is that GET parameters are appended without an initial "?", making the URL invalid and unusable. This was working correctly before the update, so it appears to be a regression.
