# Speaking at FrontFest 2017 in Moscow, Russia > I attended FrontFest 2017 conference and talked about image performance, lazy-loading, placeholders and creative SVGs. Published 2017-12-03 by José M. Pérez · https://jmperezperez.com/blog/frontfest-moscow-2017/ A couple of weeks ago I attended [FrontFest 2017](https://web.archive.org/web/20260210123124/http://2017.frontfest.ru/) in Moscow. There were around 200 attendees at Digital October, an impressive venue. I had a lot of fun and met many local developers. ![Jose M. Perez speaking at Frontfest Moscow 2017](https://jmperezperez.com/static/images/posts/frontfest-01.jpg) FrontFest is one of the several JS conferences that take place in Moscow, which has a healthy web community with several meetups that host up to 500 people. This single-day event was comprised of 5 tracks filled with talks and workshops. Most of the talks and workshops were in Russian, though there was always one talk or workshop in English at a given time. I especially liked [Blaine Cook's talk](https://web.archive.org/web/20260210123427/https://2017.frontfest.ru/lecture/3/) about UX and developer responsibility managing user authentication. I also enjoyed Mathieu's live-coding and following workshop, where we coded [a simple yet very fun game](https://github.com/p01/twinStickShooter). ## My talk about "Progressive Image Rendering" I had been playing with SVG techniques during the weeks before the event, which I had documented on [Using SVG as placeholders — More Image Loading Techniques](https://jmperezperez.com/blog/svg-placeholders). Thus, it was a great opportunity to include them in the talk. I also mentioned the [Image Decode API](https://chromestatus.com/feature/5637156160667648). I first knew about it through [Mathieu 'p01' Henri](https://x.com/p01/), who told me there were early discussions to implement it when we met at [RenderConf Oxford](https://jmperezperez.com/blog/render-conf-oxford-2017). Even though it's not widely supported I thought it was a good opportunity to talk about it. This API prevents the browser from blocking the UI when decoding an image, and can be handy when doing lazy-load. Check also [this post](https://medium.com/dailyjs/image-loading-with-image-decode-b03652e7d2d2) for an example on how to use it. ### Slides The slides are available on [slides.com/jmperez/pir-frontfest](https://slides.com/jmperez/pir-frontfest) and you can also see them right here embedded:
