How to remove img tag from gallery

Hi,

I am using custom function for my gallery but still I need some mods.

I have this:

<div class="gallery galleryid-182" id="gallery-1">
	<a title="Image title #1" href="https://image-link.com/1.jpg" rel="shadowbox[title]"><img title="Image title #1" alt="Image title #1" class="attachment-thumbnail" src="https://image-link.com/1.jpg"></a>
	<a title="Image title #2" href="https://image-link.com/2.jpg" rel="shadowbox[title]"><img title="Image title #2" alt="Image title #2" class="attachment-thumbnail" src="https://image-link.com/2.jpg"></a>
	<a title="Image title #3" href="https://image-link.com/3.jpg" rel="shadowbox[title]"><img title="Image title #3" alt="Image title #3" class="attachment-thumbnail" src="https://image-link.com/3.jpg"></a>
	<a title="Image title #3" href="https://image-link.com/4.jpg" rel="shadowbox[title]"><img title="Image title #4" alt="Image title #4" class="attachment-thumbnail" src="https://image-link.com/4.jpg"></a>
</div>

And I want to be like this:

<div class="gallery galleryid-182" id="gallery-1">
	<a title="Image title #1" href="https://image-link.com/1.jpg" rel="shadowbox[title]"></a>
	<a title="Image title #2" href="https://image-link.com/2.jpg" rel="shadowbox[title]"></a>
	<a title="Image title #3" href="https://image-link.com/3.jpg" rel="shadowbox[title]"></a>
	<a title="Image title #3" href="https://image-link.com/4.jpg" rel="shadowbox[title]"></a>
</div>

Someone help me! ??
