Topic: Are there any things we can append to a new synth's URL?

I've already asked about Share Links ( ) but I was wondering whether there are any new fragments or arguments (not sure of the correct terminology) to add to the end of the URLs of new synths besides the ones used in the embed code.

Examples include:
The #full fragment used on / to load in full screen:

The &autoPlayInterval=5000 used in the original Photosynth Technology Preview to control the speed of the slideshow

Being able to link to specific images at least, if not specific camera zoom, position, and pose as Share links enabled us to do.

For my peers, here's a little demo of how the URL used in the embed code gets modified depending on your choice of options: 
Normal View link:

Default Embed link:
(Requires click to load, but plays automatically after loaded)

Embed link Variation 1:
(Requires click to load, then requires click on Play icon to play)

Embed link Variation 2:
(Loads along with the rest of the page, plays automatically)

Embed link Variation 3:
(Loads along with the rest of the page; requires click to play.)

Just today I saw on Twitter that the Photosynth team reports that adding ?mode=movie on the end of a new synth's URL will force it to show the video preview instead the interactive synth.

Here's a test with the above synth:

Since the 2014 June 10th update to the Photosynth 2 Tech Preview ( ) the default behavior of the View page for any Tech Preview synth is to overlay the synth with the Info panel.

This can be countered by attaching the autoplay=true value to the end of the view link.

Also note that the Info overlay now applies to View links with the mode=movie switch set to true, but again you can get the original behavior by attaching the autoplay=true value.


Remember that with the Photosynth 2 viewer, when you use multiple parameters/switches/flags, the first must be attached with a question mark [?] and the second and any additional switches must be attached with an ampersand symbol [&] as shown above.

I haven't explicitly mentioned it in this thread, however if you follow the first link at the top of the discussion, you'll see that you can use the startat parameter to load into synths on specific images now.

The easiest way to get a link to a specific image in a synth is to: 
1) scroll to it
2) pull up the 'Info' pane
3) click the chain icon (currently 4th after Facebook, Twitter, and Tumblr) to get a Share link to that image
4) copy that link and paste it.


Something that only works on synths that your currently signed in account has authored is to attach #warnings to the end of the view link, which will do the same thing as if you had clicked the 'omitted' link in a synth where some photos were unable to be synthed.

Note that the only person that this link will have any effect for is andyrblank (or someone who is using a computer which is signed into his account).

The 2014 June 10th update to the Photosynth 2 Technical Preview site also added two parameters able to be used with the HTML embed code for Tech Preview photosynths.

:: showannotations
This will control whether highlights are displayed or completely hidden when the synth loads.

The default for both the View page and the Embed page seems to be to show highlights, however the Embed page does not display the highlight reel in the lower right corner for space reasons.

Default for fullscreen is currently set to false.

:: showpromo
This controls whether a short "See more on Photosynth" link is temporarily overlaid over the right hand side of the synth viewer in a small Photosynth-2-green rectangle, several seconds after the embedded synth loads. This link only appears once the first time that you play through the synth.

It mainly makes sense on synths embedded on websites other than, and for that reason does not appear to work with the View page.

Example: (Takes effect) (No observed effect)
