Subject: Fix src for images
X-Git-Tag: v0.0.2^2~20
X-Git-Url: http://cvs2.gaslightmedia.com/gitweb/index.cgi?a=commitdiff_plain;h=85635ab26e3408f05bb2d04777672c108240db7e;p=WP-Plugins%2Fglm-wp-importer.git

Fix src for images

This fixes why some images after the import aren't editable.
Finds all src tags in content and finds the images from the Media
Library to match it and places the class attribute with the wp-image
class with it's id so it can be referenced. Also fixes the size of these
images when they we're adjusted.style attribute part.
