xF1 Add-on [TH] Thumbnails 2.1.7

Installation
---------

To install this add-on, you will need to extract the zip and upload all the
files from the contained upload directory onto your web server into the root
folder of your XenForo Directory.

Having uploaded the necessary files, you should log in to the Admin Control
Panel of your XenForo Installation and click on 'Install Add-on' under the
heading 'Add-ons' on the left-hand side of the Admin Control Panel under the
'Home' tab.

Enter the following into the text box labelled 'Install from file on server':
install/data/addon-ThemeHouse_Thumbnails.xml

Alternatively, extract the zip to a folder on your local computer, and then
click 'Choose File' to locate the extracted XML file on your computer.

Upgrading
---------

To upgrade an existing add-on, you will need to extract the zip and upload all
files within the upload directory to your existing XenForo Directory,
overwriting all files.

Once the files are uploaded, your XenForo installation will automatically be
closed until the upgrade is complete. To begin the upgrade, log in to the Admin
Control Panel, where you will see a notice indicating that there are new
add-ons ready to be upgraded. Click the notice to upgrade your add-on.

Once the upgrade is complete, your XenForo installation will automatically be
reopened.

Note: the notice will not appear if you are upgrading to a fourth-point (x.x.xX)
version of the same release (i.e., from 1.1.2 to 1.1.2b) as upgrading the
database is not required.
