Вот единственный HTML-код, который вам нужен для добавления формы поиска на страницу, которая ищет в Google изображения определенного размера:
<!-- This is a search form that will take us to
https://www.google.com/search?tbm=isch&tbs=isz:ex,iszw:7680,iszh:4320&q=example
when we search for ???????. This search will show us only images, and
those images will all be 7680 pixels wide and 4320 pixels tall.
First we enclose everything in a <????> whose ?????? is everything that
the search engine results page’s URI to the left of the question mark (?)
in it -->
<form action="https://www.google.com/search" method="get">
<!-- Next, we add the arguments that are added to the Google URI. For each
part of the URI we want to build, we need an <?????> element with a
????? attribute. -->
<!-- build ???=???? -->
<!-- ??? needs to be set to ????, which tells Google we want only
image search results. We add ????="??????" to the input element
because we don’t want the end user to have to choose that
themself -->
<input name="tbm" value="isch" type="hidden">
<!-- build ???=???:??,????:????,????:???? -->
<!-- ??? needs to be set to a three-part parameter that tells Google
we’re doing a search for images of a certain size and what the
dimensions we’re looking for are -->
<input name="tbs" value="isz:ex,iszw:7680,iszh:4320" type="hidden">
<!-- build ?=??????? (but ours won’t specify "example" — the user
will decide what to search for). This parameter’s ???? is
not ?????? but rather ????, which is what we’ll ask the user to
enter. -->
<!-- If we don’t want to prompt our users’ imaginations,
we could remove ???????????="???????" -->
<!-- ????="??" means that the field where the user will input their
query is about 35 characters wide on page load -->
<input name="q" size="35" type="text" placeholder="puppies">
<!-- Finally, we add the button the user can tap to enter their query,
so our ???? is ??????. We can set our value to whatever we want
our button to say -->
<input type="submit" value="Find images of size 7680px × 4320px">
<!-- <????> is the only element we have used that we must close -->
</form>
