The 101 Pictures Gallery
Image gallery.
To be completely honest, if you're wanting to make an image gallery, you would save yourself a lot of time and trouble by using Wordpress.org

That said...
Assuming your images are stored server-side, and you really want to code this yourself, unless you want to type every image URL one by one, you may want to look into a server side language that can scan through your image folder(s), parse the paths and wrap it into HTML tags. It really varies what you can do depending on your server environment...

A few other things
&lt;a href=&quot;https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcQlaU7tH2vtUNYd3dmumnyJ47_FhXK7CU3FVAEG9dQet_iUlFMP&quot; class=&quot;&quot;&gt;
There's no point declaring class is there is not one to assign to it.
Another example:
&lt;img src=&quot;https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcQqzKPv6A_I5n6GnWWdzcU9lr1Qu6-OpTMG1tnoB9pGWN1FDaNZ&quot; alt=&quot;...&quot;&gt;
alt=&quot;...&quot; may as well be left out, if an ellipsis will be its content. Why not class=&quot;something meaningful&quot;?
