For it's not possible to change the size of embedded objects (images) inside xml fields dynamically. The only way to change the image size is to change the size in the object xml tag, however this doesn't solve the problem with having the first article with a large image.

The best to achieve this is to add a new attribute to the article class which is either an image type or a related object type.
In the view template you could for instance do (if you use image type)
{attribute_view_gui image_class=medium attribute=$object.data_map.image}
for medium images and
{attribute_view_gui image_class=small attribute=$object.data_map.image}
for small images.

For the object relation type you must change the override template for images (for instance embed_image.tpl) to handle this input, for instance

{default image_class='medium'}
{set image_variation=$object.data_map.image.content[$image_class]}
...
{/default}

You need the default tag around the whole template code, to default the value to 'medium' incase it's not specified.

embed_image.tpl:

{default image_class='medium'}
{let image_variation="true"
align="center"
href=''}

{section show=is_set($attribute_parameters.size)}
{set image_variation=$object.data_map.image.content[$attribute_parameters.size]}
{section-else}
{set image_variation=$object.data_map.image.content[$image_class]}
{/section}

{section show=is_set($attribute_parameters.align)}
{set align=$attribute_parameters.align}
{section-else}
{set align="center"}
{/section}

{section show=is_set($attribute_parameters.href)}
{set href=$attribute_parameters.href}
{section-else}
{set href=""}
{/section}

{switch match=$align}
{case match="left"}
<div class="imageleft">
{section show=$href}<a href={$href|ezurl}>{/section}
<img src={$image_variation.full_path|ezroot} />
{section show=$href}</a>{/section}

<div style="width: {$image_variation.width}px;">
{$object.data_map.caption.content.output.output_text}
</div>
</div>
{/case}
{case match="right"}
<div class="imageright">
{section show=$href}<a href={$href|ezurl}>{/section}
<img src={$image_variation.full_path|ezroot} />
{section show=$href}</a>{/section}

<div style="width: {$image_variation.width}px;">
{$object.data_map.caption.content.output.output_text}
</div>
</div>
{/case}
{case}
<div class="imagecenter">
{section show=$href}<a href={$href|ezurl}>{/section}
<img src={$image_variation.full_path|ezroot} />
{section show=$href}</a>{/section}

<div style="width: {$image_variation.width}px;">
{$object.data_map.caption.content.output.output_text}
</div>
</div>
{/case}
{/switch}

{/let}
{/default}
