Q: How do I use LinkThumbs on my web page(s) ?
A: To enable LinkThumbs on your web page(s) you need to include the following script at the bottom of your web page(s), just before the </body> tag:

<script type="text/javascript" src="http://www.screenthumbs.com/tools/js/linkthumbs.js?key=WebsiteKey&profile=ProfileName"></script>

where WebsiteKey is your website key, found in the My Websites section in your account and ProfileName is the name of one of your profiles, found in the My Profiles section in your account. The ProfileName parameter is optional, in which case the website global settings are applied (instead of profile settings).

Q: Where can I configure LinkThumbs ?
A: There are two locations where you can configure LinkThumbs, depending on whether you specified a profile name when including the script on your web pages(s) or not. If you have specified a profile name to be used, you can find the LinkThumbs configuration options in the My Profiles section in your account. Just choose a profile you want to edit and you'll find the configuration options under LinkThumbs. If no profile name was specified, the global website settings will be used. You can edit these in the My Websites section in your account. Just choose a website you want to edit and you'll find the configuration options under LinkThumbs.

Q: Why are there two places (My Profiles and My Websites) where I can configure LinkThumbs, watermarking, and so on ?
A: When including the script on your web page(s), you have the posibility to specify a profile name. When you don't specify any profile, the website settings are used (found in the My Websites section). Each website has its own settings, so you can have multiple websites with different settings. By specifying a profile, you can have different settings for each web page in your website, giving you a finner degree of control on how thumbnails are displayed in your web pages.

Q: What are the configuration options available for LinkThumbs ?
A: You can configure the links for which LinkThumbs should be enabled and also how thumbnails should be displayed. For configuring the links for which LinkThumbs should be enabled you have two options: you can check the Apply on all external links checkbox, in which case LinkThumbs will be enabled for all external links on your web page(s), or you can specify the class name(s) LinkThumbs should look for when deciding which links should have it enabled. You can use the Class Name field to specify a class name. Other options available are Hover Delay, which specifies after how many seconds should the thumbnail appear, and Hover Type, which specifies when should the thumbnail be displayed. There are three possible hover types: Link (the thumbnail appears when the user hovers the cursor on the link), Icon (a small icon will appear to the right of the link when the user moves the cursor over the link; hovering this icon will make the thumbnail appear; the icon disappears after a few seconds), and Constant Icon (works the same as Icon, except the icon is always visible).

Q: Can I have more than one class name for LinkThumbs ? If so, how ?
A: Yes, you can. You can have multiple class names for which LinkThumbs should be enabled, each with its own settings. To configure LinkThumbs for more class names, go to the My Profiles or My Websites section in your account (depending on whether you specified a profile or not when including the script on your web page(s)) and choose the profile/website you want to edit. Under LinkThumbs, you'll find the Add More Configurations link. After clicking the link you'll be asked how many configurations you want to add. Then you'll be able to specify custom settings for each class name.

Q: Can I add watermarking on thumbnails ? How ?
A: Yes, you can. Watermarking options are found in the profile or website configuration pages. If you specified a profile name when including the script on your web page(s), use the profile configuration page, by choosing a profile in the My Profiles section in your account. If no profile was specified, you can configure watermarking in the My Websites section in your account, by choosing the website you want to edit.

Q: What are the configuration options available for watermarking ?
A: You can watermark your thumbnails with a custom text and icon. The text will appear in the bottom-left corner of the thumbnail. If a custom icon is specified, it will appear to the left of the custom text (if specified, otherwise it will appear in the bottom-left corner of the thumbnail). You can upload a custom icon or specify an URL to an image (the image is downloaded only once and then stored on our servers for faster access). You can also use your site's favicon as the custom icon. All these options are available under Thumb Branding in the website configuration (or profile configuration) page in your account (My Websites or My Profiles section).

Q: How can I add PageRank on my thumbnails ?
A: PageRank can be enabled or disabled by choosing a website in the My Websites section or a profile in the My Profiles section and checking or clearing the Enabled checkbox under PageRank.

Q: What are the available parameters ?
A: We allow several on-the-fly parameters that can be specified in the requesting url. When specified, they will be applied to the resulting thumbnail image.

Parameter: width
Value: 1 - 3000
This parameter will specify the width of the resulting thumbnail image in Pixels. We recommend a range of 20 - 1500.

Parameter: height
Value: 1 - 3000
This parameter will specify the height of the resulting thumbnail image in Pixels. We recommend a range of 20 - 1500.

Parameter: quality
Value: 1 - 100
This parameter will specify the quality of the resulting image, and is a percentage number value. The higher the value, the better the quality. Please note, if the quality is high, the delivery speed is reduced. We recommend a range of 60 - 80.

Parameter: size
Fixed Values: 0, 1, 2, 3
This parameter can be used to specify one of the fixed width x height value pairs. If this parameter is used along with specified width and height parameters, this parameter will be ignored. The sizes are as follows:

• 0 = 128x192
• 1 = 256x192 (default)
• 2 = 400x300
• 3 = 640x480
  

Parameter: format
Fixed Values: 0, 1, 2
This parameter will specify the image format for the resulting thumbnail image. Format options are as follows:

• 0 = jpeg (default)
• 1 = png
• 2 = gif

Parameter: profile
Value: ProfileName
This pararmeter is used to specify which configuration profile set to use. When you have created a profile for a web page, application, or entire website that contain all the configurations you need, then you can simply use the profile parameter and appkey alone. The benefits are that you never have to change the image source url manually, and you can change the appearance of the thumbs dynamically through your ScreenThumbs account!
