Visual Arts Supplement?

I’m applying SCEA and have some questions concerning the visual arts supplement. I’ve viewed some old posts (2004 or so?) and they mention things like mailing the actual art in or burning them into a CD and sending the physical CD in… Is it all online now? This is separate from slideroom right? (I also know nothing of slideroom…) I noticed that I can’t actually access the arts supplement page until after I submit the application, but I want to make sure I can match the guidelines before indicating that I wish to submit one. Has anyone submitted their common app already and seen the 2015 guidelines to submitting a VISUAL arts supplement? i.e. do the pieces all have to match a single theme or can they be unrelated and works on their own?
How exactly do we submit them - take photos and upload the photos? I saw somewhere that someone put them all into a PDF and wrote descriptions underneath each. And they included an art teacher’s rec in the visual arts supplement - is that the norm, for such a letter to accompany the art, and should I ask for one then?
I have a mixture of digital, oil, and graphite works but I do need to get them all photographed soon… hmm… should they come in a pdf or jzip folder or…
thanks in advance!!

You should be able to get your questions answered by looking at the Class of 2019 guidelines, and yes you need to get a LOR and write an Art specific resume, so you could get started on both of those. And jpeg-20 image limit.

so I’m on the online arts supplement page and I want to include a mixture of paintings, pastels, graphite, charcoal, and digital (go across the board I guess?) but it tells me to choose a category first - does that mean that I’d be submitting multiple arts supplements to fit in the categories (i.e. one for painting, one for drawing, and one for other)
