All modern browsers are supported as well as Internet Explorer 8 and above.

If you run into problems with IE8, IE9 or IE10 and get a error message saying IE7 is not supported, it may be because you are running the browser in IE7 compatibility mode. Here are directions on how to change the compatibility mode.

If you're using a Google Spreadsheet as your source, make sure your Google spreadsheet is public and published. Also make sure you don't have any empty rows in the spreadsheet as this can sometimes cause problems.
Yes, but the photos must be publically available online and the URL must end in .jpg, .png, or .gif. Some users have found that uploading images to Dropbox is an easy and convenient way to give them a URL that’s compatible with TimelineJS.
TimelineJS is optimized for 20-30 entries. If you have more entries, you run a risk of slow load times. Test your timeline to make sure you are satisfied. The best remedy for slow load times may be to edit your timeline to include fewer entries or to create a series of smaller timelines. That said, some publications have built timelines that have hundreds of entries.
You can change the height using the embed tool above. If you need more control, read the Google Groupdiscussion to learn more.
Yes. See here.
You can change the font using the embed tool above. If you’d like to make modifications that aren’t supported by embed tool you’ll need to dig in to the CSS — here's a discussion that includes a few tips.
If this is your end goal it may be easier for you to use a slider tool rather than TimelineJS. Here are a few ways you can remove the timeline bar.

The TimelineJS iFrame embed method is compatible with WordPress. Some WordPress installs require users who want to paste code in to the HTML view to have an editor or administrator status — if you’re having trouble, make sure that you have sufficient permissions.

If you don't have the right permissions, try this plugin for Wordpress.

Thumbnails are only shown from Flickr, Youtube, Vimeo etc. That was done for performance reasons. Having a very large image file as a thumbnail really slows down the timeline. Flickr, Youtube etc have actual thumbnail sized images that can be used that don't cause performance issues. You can also create your own thumbnails.
Yes. See here for a hacking idea.
Yes. See how here.
The display of the timeline is dynamic. It chooses a time interval that best matches the number of events there are with the amount of time that is covered.
Tags are essentially categories. You can have up to 6 of them to categorize events on the timeline. The events on the timeline will align with their category row. See the screenshot below
Not at the moment.
The default number of rows is three. If you are using tags and you have more than three tags, the number of rows increases to six.

If you’re using the TimelineJS Google spreadsheet template, first make sure the cell you want to modify is set to Plain Text — "Format > Number > Plain Text.” Then simply enter the year (e.g. 1994) or month and year (e.g. 7/1979).

Earlier versions of TimelineJS required you to enter a date as January 1 of a given year to do this, but now you should just enter the full year, as explained above.

You can add B.C. dates by using negative years. For example, -100 would be 100 B.C. Be sure to change the formatting of the cell you want to modify to Plain Text — "Format > Number > Plain Text".
No. TimelineJS uses Google's API to access the data from the Google Spreadsheet. If you want to start your work in Excel and then copy and paste your data into a Google spreadsheet, that’ll work but the likelihood of errors increases.
Yes. JSON is the best and safest format for feeding information into TimelineJS from a database. Just use your language of choice to create a json file from your database.
Yes! Just grab a copy of the template and replace the language with the language you want to create. You can find your language's two letter code here. Save the file and post it to the Google Group or you can do a pull request on GitHub.
You can include a link in the text field using the standard HTML for a hyperlink.
