Hello,
I see .. maybe your image "tag" bigger that 50 character, that's why you can't insert the image tag, since machform only allow 50 characters.
Anyway you can do some modification to make the limit size bigger, to do so you need to edit "edit_form.php" and "db-functions.php" file. Try to follow these steps :
1. Edit your "edit_form.php" and go to around line 652, you will see this code :
<input id="form_title" class="text medium" value="" tabindex="1" maxlength="50"
onkeyup="update_form(this.value, 'name')"
onblur="update_form(this.value, 'name')" type="text">
replace with this
<input id="form_title" class="text medium" value="" tabindex="1" maxlength="100"
onkeyup="update_form(this.value, 'name')"
onblur="update_form(this.value, 'name')" type="text">
2. Edit "db-functions.php" and go to around line 51, you will see this code :
$rules['form_name']['max'] = 50;
change it to
$rules['form_name']['max'] = 100;
