Now that's funny right there.

I cleaned this thread of the nonsense.

Does a dream also has to be no longer than 15 seconds If the animation Isn`t made from a video but from a jpg? (sorry my bad english I write from germany)

If you own the copyright of the image, it can be as long as you want.

If you are using a stock image,  it can be as long as you want but you have to include proof that you have permission to use the image.

If you do not own the copyright of the image and can not get permission to use it, you can not post a dream created by it.

Proof would be a screen shot of an email or forum post giving permission. You would need to create a zip of your dream and proof of permission and upload it as the dream.

Edit: I am not a Stardock Employee and do not represent them. If I am incorrect, someone will probably post a correction to the above.

CarGuy1 is correct...

Can I publish a dream using famous art pieces from dead artists? example: (Vincent Van Gogh)

Or would that be against the guidelines?

If you take a photo of the art you'd be OK, however if you 'borrow' it from a publication/book/website/etc the reality is that specific reproduction of the artwork will be copyright to the photographer and/or the publication.

As with any claimed 'royalty-free or free-to-use image available on the net....they would then be OK...

Well it's a moving version of the art that I found on youtube and not an exact copy of the real thing so I don't know if it would be ok or not....

Guess I will try to submit it and see if it gets rejected or not.

It looks like your planned usage would require written permission.

I just uploaded a few dreams based on the movie interstellar and now they are gone....is this a no no? ....if so it leaves me scratching my head as i see plenty of stuff based on movies and video games all over this website.

You hould have received a rejection email with the reason why.

Please check your email spam folder if you haven't.

reason says i can only use 15 seconds of something i didnt completely make....which is confusing as i only used 3 seconds for both of them, and neither of them broke 15 seconds in length. ....i used 2 scenes from the movie that are only about 54 frames in length. (less than 3 seconds)

I guess i should take that as a compliment, as they thought the length was natural, but they obviously didnt read my about section, or they would have read the explanation there. 

i mean, one of them was 5 seconds in length total

You can re submit and I will ask that moderator to take another look.

I too had a submission rejected but the only reason listed in the email was a link to the guidelines.  I'm trying to understand precisely which aspect was against the guidelines.  The dream was only 5 seconds of a clip from a video game.  I listed all author information as the company that created the game including a link to their website.  What really confuses me is there are other clips already on Wincustomize from the same game so I assumed it fell under the fair use policy.

Here is what you said in the author comments...

A dream I converted for myself from the Warcraft burning legion that I wanted to share with the community.

The resolution is large enough to spread across multiple displays but looks best on a single monitor (or mirrored) using Fit or Fill adjustment.

Heres what was told to you.....

***You need to provide the URL to the site this was taken from so we may check to make sure they gave permission for you to use this.***

Not sure what is hard to figure out!  Maybe you didn't finish reading it.

I see.  The first submission didn't appear to have taken, so I uploaded a second time and received 2 emails simultaneously early in the morning.  One had the reason for rejection and the second didn't.

Anyway, I just want to work through that so I can hopefully share this with other fans;  Much like AzDude in his Warcraft dream https://www.wincustomize.com/explore/dream/6877/

The URL is in the Dream properties.  I credited them in the Dream itself.  Should I also provide that in the upload comment section?  

What happened to the dreams? I have been gone for a while, and it seems most of the dreams being posted now are just copies of another company's animated desktops? I understand "fair use", but if a commercial company is making and selling animated desktops and you simply copy a video of their animated desktop and rerelease it as a dream, that seems almost like a ripoff of their product? Is this allowed now?

The rules were established in 2007.  See the Op.

Nothing has changed...

if i understand correctly, ShiningSquirrel is asking about this part of the WC rules:

https://www.wincustomize.com/explore/dream/7289/ for example is using copyrighted material by 3Planesoft, a company that is making money with animated wallpapers/screensavers. http://www.3planesoft.com/fish-screensavers/caribbean-islands-3d-screensaver/ 

imho the whole gallery is a big ripfest caused by obsessive compulsive disorder. there is also some few nice original content that can hardly be found.

moshi....this thread/post IS the specific Guidelines for Dreams Submissions, hence its title....
