How to make product image required?

Question

Currently creating a product doesn't need any image. How do I make it required? Using javascript is ok. I know how to do it with input text field, but image is quite different.

You can try to add some class for the field media_gallery_content_save and then to validate it as you check it to be != []. For example in app/design/adminhtml/default/default/template/catalog/product/helper/gallery.phtml replace this:

<input type="hidden" id="<?php echo $_block->getHtmlId() ?>_save" name="<?php echo $_block->getElement()->getName() ?>[images]" value="<?php echo $_block->htmlEscape($_block->getImagesJson()) ?>" />

with this:

<input type="hidden" id="<?php echo $_block->getHtmlId() ?>_save" name="<?php echo $_block->getElement()->getName() ?>[images]" value="<?php echo $_block->htmlEscape($_block->getImagesJson()) ?>" class="required-entry-image" />

and in app/design/adminhtml/default/default/template/catalog/product/edit.phtml replace this:

Validation.addAllThese([
    ['validate-super-product-attributes', '<?php echo Mage::helper('catalog')->__('Please select one or more attributes.') ?>', function(v) {
                return (v != "no-attributes");
            }]]);

with this:

Validation.addAllThese([
    ['validate-super-product-attributes', '<?php echo Mage::helper('catalog')->__('Please select one or more attributes.') ?>', function(v) {
                return (v != "no-attributes");
            }],
    ['required-entry-image', '<?php echo Mage::helper('catalog')->__('This is a required field.') ?>', function(v) {
                return (v != "[]");
            }]]);

Of course it's better not to change it in the core files.
