Hi guys,

Probably have a bug on a tracking by image, when I use image tracking link, always don't get resolution, then display as unknown, if I change to JavaScript Tracking Code, works fine.

I don't know if this is a bug or limitation on image tracking link, then, I open this issue.

Image tracking can't provide any metrics that can only be collected using javascript. This contains resolution, browser plugins, etc.

Hi guys,

@sgiehl then I think that is good and important do add on https://developer.piwik.org/api-reference/tracking-api or on a trackingCodeGenerator action information about this limitations, isn't?

Hi @joubertredrat

this is documented in: https://piwik.org/docs/tracking-api/#image-tracker-code

Note: the code doesn’t use Javascript so Piwik will not be able to track some user information such as search keywords, referrers, screen resolutions, browser plugins and page titles. The image tracker code also does not create first party tracking cookies which results in some information being lost.

Also just added this in the FAQ How do I enable tracking for visitors that have disabled Javascript?
