    38382. Activate the plugin through the 'Plugins' menu in WordPress.
    39393. Specify your connection settings through the settings menu in WordPress (a new submenu called 'picasaView' should have appeared).
    40 4. Place `[picasaView]` in you content to view all your public albums. That's all.
    41 5. If you like to view a specific album, use `[picasaView album='ALBUMNAME']`. Instead of the album name you can also use the unique album id.
     404. Place `[picasaView]` in you content to view all your public albums. That's all.
     415. If you like to view a specific album, use `[picasaView album='ALBUMNAME']`. Instead of the album name you can also use the unique album id. The album name is the one that you see in the addressbar of your browser when entering your album on picasaweb (may be different from what you entered as album name when creating the album. For example, if it's `http://picasaweb.google.de/simon.sattes/PicasaViewDemo`
     42then the album name was `PicasaViewDemo`.
    4243If your album name contains a single quote use double quotes for the name: `[picasaView album="ALBUMNAME'S"]`.
    43 It's now possible to link different people's albums in your blog by specifying the attribute user like this: `[picasaView user="USERNAME"]`. This will override
    44 the user-setting from your picasaView admin panel. Of course you can also use a combination of the user and the album:
    45 `[picasaView user='USERNAME' album="SIMON'S TESTALBUM"]`. The use of single oder double quote can be mixed like in this example.
     446. new in v1.0: if you like to show the images of one album directly in a post, use the option "instantView":
     45    e.g. `[picasaView album="ALBUMNAME'S" instantView]`
    4646
     47It's possible to overwrite all settings on the admin-options page with each picasaView-tag. That gives you the possibility to view all possible albums of different users on your blog. These are the options that can be used
     48in the tag.
     49
     50NOTE: you can combine all options as you like and use as many of them as necessary. **If an option is missing, the general setting from the admin options page will be used instead.**
     51
     52* `album`: the name of the album you'd like to view
     53* `instantView`: if specified, the album images are shown directly in the post. Can only in combination with `album`
     54* `userId`: the user-Id from piasaweb
     55* `server`: the URL of the picasaView server
     56* `thumbnailSize`: the size of the thumbnails. May be one of the following values: `32, 48, 64, 72, 144, 160, 200, 288, 320, 400, 512, 576, 640, 720, 800`
     57* `imageSize`: the size of the full images. May be one of the following values: `200, 288, 320, 400, 512, 576, 640, 720, 800, 1024, 1152, 1280, 1440, 1600` (note: 1024 and above will currently not work due to limitations of the picasaweb-service)
     58* `imagesPerPage`: how many images should be shown at one page. If the album contains more images than this setting, paging is enabled
     59* `cropThumbnails`: if set to `yes`, the thumbnails will be cropped, if `no`, they won't (note: only works with a thumbnail size smaller than 200)
     60* `showDebugOutput`: shows more information on what went wrong (if an error occured).
     61* `rssLookupType`: overrides the default lookupType. May be set to one of the following values: `curl, socket, file_get_contents`
     62
     63A combination could be `[picasaView user="USERNAME" imagesPerPage='6' cropThumbnails='yes']`.
