Thread: First image required

First image required

Hi,

I need to make one image required when creating an ad.

I checked out this thread which says add "class=”required” to “step-functions.php” line 205" [thread now closed]. That seems to have worked for a number of people

I've tried throwing that code in at and around line 205 and it doesn't seem to work for me. I know absolutely nothing about coding so it may be down to me.

Could someone please let me know the exact code that needs to be added and where?

I am using CP 3.1.6

Thanks so much in advance.
