We had multiple cases where people thought it was a good idea to upload full size jpegs for posts, which gives us 8-23MB! jpeg files.
I think for most discussions it is more than enough to limit our self to 1920x1080 or smaller resolution.
This does not apply to raw files of course.
Also it might also help to not use the “upload file” function for image files. just drag’n’drop them into the post.
Thank you in advance
I’m happy to do that, of course. However, for PlayRaws this means that you can’t really judge noise reduction or the generation of halos anymore (makes processing easier 
).
Does the site need more financial support to carry the file storage?
part of the problem seems to be how people upload the images … some of the threads dont have thumbnails for the files that everyone looking at the threads downloads 33mb in 3 jpegs for just viewing the thread.
Yes, I just checked this post. Originally, I uploaded the image using the corresponding icon and the “thumbnail” had the size of the complete image (~6 MB). When I dragged the same image into the post I got a thumbnail of ~ 0.7 MB.
Can this be fixed in the forum software? This behavior was not predictable for me.
This is a good question. Ideally it should create a thumbnail regardless of which upload method is used.
I personally don’t mind the image sizes (this is a photo forum after all, and @Thomas_Do makes a good point about judging quality of some effects at full resolution).
I’ll test the upload stuff shortly and see what’s going on.
For what it’s worth, in a recent post (What's In Your Bag? - #44 by anarcat) I have done the “drag and drop” thing in the hope it would do the right thing, but the “thumbnail” was also that huge file. I have since then re-uploaded a 1080p-maxed picture to reduce the pain.
It would sure be nice to have the full resolution images available on click while keeping threads with more reasonable thumbnails… I haven’t looked at discussions on discourse on the topic, but it seems to me this should be fixed (or reported) upstream! 
Hm, could we, please, limit ourselves to 4.740 x 3.260 or bigger? Everything else would make next year’s PlayRaw Calendar much more difficult … 
I’ve still got a note to investigate what might have been going on - usually the forum generates thumbnails/previews that are not full-resolution unless clicked on.
whoops…my apologies, I do believe this is probably over the image of my photo ‘bag’ that I copy/pasted from amazon without thinking how big it was…do you need me to take it down?
@lizardbreath - no problem at all! It’s not your image that’s the problem. 
well that’s good to know :)
I’m surprised that in the age of 8 core smartphones with resolution bigger than FullHD we talk about 1920x1080
If traffic is a problem, JS should check file size before even accepting it. If storage is a problem — server side resize can be performed.
not every user on a mobile connection has unlimited bandwidth in their contract or LTE every time.
Why do you download full sized attachments then?
The thing that concerns me when posting anywhere is the intended use of the depiction. And, for web viewing I really want to do the scaling myself. Having some server or browser arbitrarily select the interpolation algorithm invites image quality problems. Also, if I were particularly concerned with how my images were to be used by unsanctioned parties, I’d rather them have to wrestle with a small image. So, for most web regarding, I resize to 800x600 or thereabouts, unless the composition begs to be viewed larger. In any case, never more than what would accommodate a 10-15 degree viewing angle, which I believes accomodates the average desk-oriented viewing condition.
Here, we have an appetite to inspect others’ IQ, particularly in PlayRaw, and @chris has a resolution requirement for the calendar, so there’s a need to provide larger. For PlayRaw, I’ll still not post a composition larger than a single display; @chris, I think it’d serve your need well to ask folk for a separate rendition for the calendar, sized appropriately…
Regarding smartphones, the largest seems to be the Samsung Galaxy S6, 1440x2560px:
Still, a bit smaller than my D7000 images…
I must admit that the correct way would be to talk to people in advance and ask for the required resolution, as you suggested. Unfortunately, that did not fit my last minute conditions I had during the last years. Maybe this year I’ll start a bit earlier. But I must admit that personal correspondence to more than a dozen people worries me a bit as a non-native speaker. Answering or posting in the public part of the forum is still something else than personal messages.
But for me there is a reasons that anyway speaks for high resolution images in the threads: The things we post here are under a cc license anyway (I guess unless noticed otherwise), and e.g. in the PlayRaw threads, there is even a raw image available cc licensed. Giving away cc licensed images means that others should be able to use the picture given they follow the licenses requirements. What sense does it make then, to post a low resolution image? Does it say “yes, I give this away cc licensed, but I give you only the resolution to print on a stamp, not the resolution to print big and hang it on the wall in your home”?
IMO the traffic problem has to be solved technically, such that only when download is clicked (or the web view is clicked to enlarge the image), the full resolution should be delivered by the server. If this is not yet possible, an upstream bug has to be filed against discourse. If I do not want to allow people to hang my cc licensed images on their walls, I am still able to upload lower resolution, but this should IMO not be the forum’s general policy.
Yes, pretty much. “Copyright” as an artifact of agreement applies to a “work”. In our realm, that work is the depicted image in all of it’s glory (or lack of). If I choose to publish my work in a particular resolution, that’s my choice as the creator. If I then attach a license to it, you now know the terms under which you can use (or not) that work.
So, if one were to take one of my CC-licensed 800x600 proof JPEGs, blow it up to 4’x8’ and hang it in their living room with the appropriate attribution, that’s their allowable choice under that license. Some of my stuff is overprocessed for effect, so that might even look good. If they contacted me for a higher-resolution image, I’d then entertain producing another depiction, with appropriate license. I was contacted thusly about a year ago regarding one of my images taken as a snapshot at the inquirer’s property, chose not to because the particular image really wasn’t of the resolution suitable for their intended depiction (gee, I need a D850… 
).
I hope this doesn’t come across as an attitude, I just want to make sure folk really understand what a copyright license really means. Some of the discussion around folks’ recent posting illustrated to me that this understanding isn’t pervasive…
Oh, back to my original post, to me it make sense under certain considerations:
For me, #1 and #3 are predominant considerations, #3 for when I travel and have to put up with dodgy hotel wifi. But, if I were doing imaging for a living, I’d probably factor some consideration of #2 into my workflow. I’m not that good at it, so that’ll probably not come to pass…
I don’t want to make more work for @chris, but sidecar files should be posted with play raw images, so free software + cc licensed sidecar and raw file = you can get the hirez image
