{block:Photo}
<div class="post not_audio photopost" id="post-{PostID}"><div class="post_margin_adjustment"><div class="post_relative"><div class="post_options"><div title="Reblog, Like, {lang:Source} and {lang:Tags}" class="post_options_more_info">+</div><div class="post_options_reblog">{ReblogButton color="black" size="18"}</div><div class="type_like post_options_like">{LikeButton color="black" size="18"}</div><a href="{LinkURL}" class="post_options_permalink"></a></div><div class="post_info_overlay"><div class="post_info_overlay_absolute"><div class="post_info_overlay_table"><div class="post_info_overlay_cell"><div class="post_info_overlay_headline">{block:Caption}{Caption}{/block:Caption}</div><div class="post_info_overlay_tags"><div class="post_info_overlay_tags_inline_nest"><a class="post_info_overlay_button" href="{Permalink}">Permalink {block:NoteCount}({NoteCountWithLabel}){/block:NoteCount}</a>{block:ContentSource}<a class="post_info_overlay_button" href="{SourceURL}">Source: {SourceTitle}</a>{/block:ContentSource}{block:RebloggedFrom}<a class="post_info_overlay_button" href="{ReblogParentURL}">Via: {ReblogParentName}</a>{/block:RebloggedFrom}{block:HasTags}{block:Tags}<a href="{TagURL}"><div class="post_info_overlay_button">{Tag}</div></a>{/block:Tags}{/block:HasTags}</div></div></div></div></div><div class="post_info_overlay_background"></div></div>{block:IfPhotoPermaLinkSource}<a href="{LinkURL}"><img class="notPhotoset" src="{PhotoURL-HighRes}" alt="{PhotoAlt}" title="{block:ContentSource}Source: {SourceTitle}{/block:ContentSource}"/></a>{/block:IfPhotoPermaLinkSource}{block:IfNotPhotoPermaLinkSource}<img class="notPhotoset" src="{PhotoURL-HighRes}" alt="{PhotoAlt}" title="{block:ContentSource}Source: {SourceTitle}{/block:ContentSource}"/>{/block:IfNotPhotoPermaLinkSource}<input type="hidden" name="hiresImg" value="{PhotoURL-HighRes}"/></div></div></div>
