You might want to offer a paid tier with much higher size limits and other perks like mass uploads (read, tons of files at once), it will help you pay for the bandwidth.
I agree that this is a needed service, I used to use Imageshack but they have since become a pay-only service if you want to use for so much as hotlinking images.
We may oneday add some paid features but we despise people who offer free services and the good stuff is paid. You can subscribe monthly to us if you want, Its under the āSupport Usā tab or you can just donate 1 time.
I agree in that people shouldnāt be made to feel limited in what they can do if they donāt pay, but Iām thinking that the majority of people will simply want a place where they can hotlink files and images onto forums and other sites with no loss of quality, no ad spam, and no worries about bandwidth.
It would be a lot like Imageshack when they were starting out (you could upload all the images you want without registering and hotlink to them on other websites, only your site also covers .blend files).
Depending on how the donations go, you may have to find other ways to pay for the bandwidth once it grows to a certain point (since the expenses will rise), which is where the paid tier can be a possibility.
We havenāt decided on which one to use but we were looking at blend4web earlier today, We havenāt looked in to the commercial usage of it yet though.
As of now we do not plan on deleting images any time soon but if this gets popular we may start deleting images after they have been on the server for a few months.
PasteAll retention info says
How long my pastes are being kept online
When you paste, just assume that it will be here forever, but consider that it may be gone in a second! We might delete really old posts in the future or something out of our reach could happen resulting in loss of data
For blend files it is 2 months
If you want more permanent image/file linking just use something established like dropbox, google drive, onedrive sharing. Seen similar blend file host sites come and go, when they go they destroy all the file links. While the intentions may be solid, there is no assurance this site it will still exist in 12 months time. Donāt care about short term disposable links but long term, not worth the risk, and for short term links, what are the benefits over current options that I already know serve this purpose
Then the fullscreen button will be visible in the web player UI.
Are you planning to support the JSON format? That probably could be done by uploading a ZIP package containing all the exported files + textures. The JSON files could be played back by a web player as seen above.
Keep going, hope your service will become more popular than Sketchfab or p3d.in;).
We have been looking in to some more advanced stuff with blend4web but we still have a few kinks that need to be ironed out before we add more features (fixing bugs and making sure everyones file works without acting weird).
But json and fullscreen is on our list of things to do Thanks ya
