If your looking for simplicity to add images to your WordPress blog. Install Fancyzoom, click and add then activate. FancyZoom works by zooming out your pictures instantly without navigating from your WordPress website. Just insert a thumbnail and when the picture inserted onto your WordPress blog, click it and it will zoom in, add captions too! You can download Fancyzoom directly from Panic’s blog. Look at how tiny this picture looks in this blog. It saved me tons of space and it looks much nicer in my WordPress blog. Simply click on the image to activate Fancyzoom. I love it! The only downside to this plugin is that it may stop working in older post or it may conflict with other WordPress plugins. FancyZoom will conflict with these two WordPress plugins. Instead of zooming in the plugin will zoom out. Oh well it was good while it lasted. There are sooo many WordPress photo manager plugins for your WordPress blog. I have yet to find a favorite besides the Flickr Manager.
